| MCP6271/1R/2/3/4/5 170 A, 2 MHz Rail-to-Rail Op Amp Features * * * * * * * Gain Bandwidth Product: 2 MHz (typical) Supply Current: IQ = 170 A (typical) Supply Voltage: 2.0V to 6.0V Rail-to-Rail Input/Output Extended Temperature Range: -40C to +125C Available in Single, Dual and Quad Packages Parts with Chip Select (CS) - Single (MCP6273) - Dual (MCP6275) Description The Microchip Technology Inc. MCP6271/1R/2/3/4/5 family of operational amplifiers (op amps) provide wide bandwidth for the current. This family has a 2 MHz Gain Bandwidth Product (GBWP) and a 65 Phase Margin. This family also operates from a single supply voltage as low as 2.0V, while drawing 170 A (typical) quiescent current. The MCP6271/1R/2/3/4/5 supports rail-to-rail input and output swing, with a common mode input voltage range of VDD + 300 mV to VSS - 300 mV. This family of op amps is designed with Microchip's advanced CMOS process. The MCP6275 has a Chip Select input (CS) for dual op amps in an 8-pin package and is manufactured by cascading two op amps (the output of op amp A connected to the non-inverting input of op amp B). The CS input puts the device in low power mode. The MCP6271/1R/2/3/4/5 family operates over the Extended Temperature Range of -40C to +125C, with a power supply range of 2.0V to 6.0V.

This is a CMOS, Schmitt triggered input that places the part into a low power mode of operation. 3.2 Analog Inputs 3.5 Power Supply Pins The positive power supply (VDD) is 2.0V to 6.0V higher than the negative power supply (VSS). For normal operation, the other pins are at voltages between VSS and VDD. Typically, these parts are used in a single (positive) supply configuration. In this case, VSS is connected to ground and VDD is connected to the supply. VDD will need bypass capacitors. The non-inverting and inverting inputs are high impedance CMOS inputs with low bias currents. 3.3 MCP6275's VOUTA/VINB+ Pin For the MCP6275 only, the output of op amp A is connected directly to the non-inverting input of op amp B; this is the VOUTA/VINB+ pin. This connection makes it possible to provide a CS pin for duals in 8-pin packages. DS21810F-page 12 (c) 2008 Microchip Technology Inc. MCP6271/1R/2/3/4/5 4.0 APPLICATION INFORMATION The MCP6271/1R/2/3/4/5 family of op amps is manufactured using Microchip's state of the art CMOS process, specifically designed for low cost, low power and general purpose applications. The low supply voltage, low quiescent current and wide bandwidth make the MCP6271/1R/2/3/4/5 ideal for battery powered applications. dump any currents onto VDD. When implemented as shown, resistors R1 and R2 also limit the current through D1 and D2. VDD D1 V1 R1 V2 R2 R3 VSS - (minimum expected V1) 2 mA VSS - (minimum expected V2) R2 > 2 mA R1 > D2 MCP627X VOUT 4.1 4.1.1 Rail-to-Rail Inputs PHASE REVERSAL The input devices are designed to not exhibit phase inversion when the input pins exceed the supply voltages. Figure 2-34 shows an input voltage exceeding both supplies with no phase inversion. 4.1.2 INPUT VOLTAGE AND CURRENT LIMITS The ESD protection on the inputs can be depicted as shown in Figure 4-1. This structure was chosen to protect the input transistors, and to minimize input bias current (IB). The input ESD diodes clamp the inputs when they try to go more than one diode drop below VSS. They also clamp any voltages that go too far above VDD; their breakdown voltage is high enough to allow normal operation, and low enough to bypass quick ESD events within the specified limits. FIGURE 4-2: Inputs. Protecting the Analog It is also possible to connect the diodes to the left of the resistor R1 and R2. In this case, the currents through the diodes D1 and D2 need to be limited by some other mechanism. The resistors then serve as in-rush current limiters; the DC current into the input pins (VIN+ and VIN-) should be very small. A significant amount of current can flow out of the inputs (through the ESD diodes) when the common mode voltage (VCM) is below ground (VSS); see Figure 2-32. Applications that are high impedance may need to limit the usable voltage range. VDD Bond Pad VIN+ Bond Pad Input Stage Bond V - IN Pad 4.1.3 NORMAL OPERATIONS VSS Bond Pad FIGURE 4-1: Structures. Simplified Analog Input ESD In order to prevent damage and/or improper operation of these amplifiers, the circuit must limit the currents (and voltages) at the input pins (see Absolute Maximum Ratings at the beginning of Section 1.0 "Electrical Characteristics"). Figure 4-2 shows the recommended approach to protecting these inputs. The internal ESD diodes prevent the input pins (VIN+ and VIN-) from going too far below ground, and the resistors R1 and R2 limit the possible current drawn out of the input pins. Diodes D1 and D2 prevent the input pins (VIN+ and VIN-) from going too far above VDD, and The input stage of the MCP6271/1R/2/3/4/5 op amps uses two differential CMOS input stages in parallel. One operates at low common mode input voltage (VCM and the other at high VCM. With this topology, the input operates with VCM up to 0.3V past either supply rail (see Figure 2-7 and Figure 2-10). The input offset voltage (VOS) is measured at VCM = VSS - 0.3V and VDD + 0.3V to ensure proper operation. The transition between the two input stage occurs when VCM VDD - 1.1V (see Figure 2-3 and Figure 26). For the best distortion and gain linearity, with noninverting gains, avoid this region of operation. 4.2 Rail-to-Rail Output The output voltage range of the MCP6271/1R/2/3/4/5 op amps is VDD - 15 mV (minimum) and VSS + 15 mV (maximum) when RL = 10 k is connected to VDD/2 and VDD = 5.5V. Refer to Figure 2-17 for more information. (c) 2008 Microchip Technology Inc. DS21810F-page 13 MCP6271/1R/2/3/4/5 4.3 Capacitive Loads 4.4 MCP6273/5 Chip Select Driving large capacitive loads can cause stability problems for voltage feedback op amps. As the load capacitance increases, the feedback loop's phase margin decreases and the closed-loop bandwidth is reduced. This produces gain peaking in the frequency response, with overshoot and ringing in the step response. A unity gain buffer (G = +1) is the most sensitive to capacitive loads, though all gains show the same general behavior. When driving large capacitive loads with these op amps (e.g., > 100 pF when G = +1), a small series resistor at the output (RISO in Figure 4-3) improves the feedback loop's phase margin (stability) by making the output load resistive at higher frequencies. The bandwidth will be generally lower than the bandwidth with no capacitive load. The MCP6273 and MCP6275 are single and dual op amps with Chip Select (CS), respectively. When CS is pulled high, the supply current drops to 0.7 A (typical) and flows through the CS pin to VSS. When this happens, the amplifier output is put into a high impedance state. By pulling CS low, the amplifier is enabled. The CS pin has an internal 5 M (typical) pulldown resistor connected to VSS, so it will go low if the CS pin is left floating. Figure 1-1 shows the output voltage and supply current response to a CS pulse. 4.5 Cascaded Dual Op Amps (MCP6275) - VIN MCP627X + RISO VOUT CL The MCP6275 is a dual op amp with Chip Select (CS). The Chip Select input is available on what would be the non-inverting input of a standard dual op amp (pin 5). This pin is available because the output of op amp A connects to the non-inverting input of op amp B, as shown in Figure 4-5. The Chip Select input, which can be connected to a microcontroller I/O line, puts the device in low power mode. Refer to Section 4.4 "MCP6273/5 Chip Select (CS)".

Figure 4-4 gives recommended RISO values for different capacitive loads and gains. The x-axis is the normalized load capacitance (CL/GN), where GN is the circuit's noise gain. For non-inverting gains, GN and the Signal Gain are equal. For inverting gains, GN is 1+|Signal Gain| (e.g., -1 V/V gives GN = +2 V/V). 1,000 Recommended RISO ( ) VOUTB FIGURE 4-5: Cascaded Gain Amplifier. 100 GN = 1 V/V GN = 2 V/V GN 4 V/V 10 10 100 1,000 10,000 Normalized Load Capacitance; CL / GN (pF) The output of op amp A is loaded by the input impedance of op amp B, which is typically 10136 pF, as specified in the DC specification table (Refer to Section 4.3 "Capacitive Loads" for further details regarding capacitive loads). The common mode input range of these op amps is specified in the data sheet as VSS - 300 mV and VDD + 300 mV. However, since the output of op amp A is limited to VOL and VOH (20 mV from the rails with a 10 k load), the non-inverting input range of op amp B is limited to the common mode input range of VSS + 20 mV and VDD - 20 mV. FIGURE 4-4: Recommended RISO Values for Capacitive Loads. After selecting RISO for your circuit, double check the resulting frequency response peaking and step response overshoot. Modify RISO's value until the response is reasonable. Bench evaluation and simulations with the MCP6271/1R/2/3/4/5 SPICE macro model are helpful. DS21810F-page 14 (c) 2008 Microchip Technology Inc. MCP6271/1R/2/3/4/5 4.6 Unused Amplifiers VIN- VIN+ VSS An unused op amp in a quad package (MCP6274) should be configured as shown in Figure 4-6. These circuits prevent the output from toggling and causing crosstalk. In Circuit A, R1 and R2 produce a voltage within its output voltage range (VOH, VOL). The op amp buffers this voltage, which can be used elsewhere in the circuit. Circuit B uses the minimum number of components and operates as a comparator. 1/4 MCP6274 (A) VDD R1 VDD VREF 1/4 MCP6274 (B) VDD Guard Ring FIGURE 4-7: for Inverting Gain. 1. Example Guard Ring Layout R2 R2 V REF = V DD -----------------R1 + R2 2. FIGURE 4-6: Unused Op Amps. 4.7 Supply Bypass With this family of operational amplifiers, the power supply pin (VDD for single supply) should have a local bypass capacitor (i.e., 0.01 F to 0.1 F) within 2 mm for good, high frequency performance. It also needs a bulk capacitor (i.e., 1 F or larger) within 100 mm to provide large, slow currents. This bulk capacitor can be shared with nearby analog parts. For Inverting Gain and Transimpedance Amplifiers (convert current to voltage, such as photo detectors): a) Connect the guard ring to the non-inverting input pin (VIN+). This biases the guard ring to the same reference voltage as the op amp (e.g., VDD/2 or ground). b) Connect the inverting pin (VIN-) to the input with a wire that does not touch the PCB surface. Non-inverting Gain and Unity Gain Buffer: a) Connect the non-inverting pin (VIN+) to the input with a wire that does not touch the PCB surface. b) Connect the guard ring to the inverting input pin (VIN-). This biases the guard ring to the common mode input voltage. 4.8 PCB Surface Leakage In applications where low input bias current is critical, Printed Circuit Board (PCB) surface leakage effects need to be considered. Surface leakage is caused by humidity, dust or other contamination on the board. Under low humidity conditions, a typical resistance between nearby traces is 1012. A 5V difference would cause 5 pA of current to flow. This is greater than the MCP6271/1R/2/3/4/5 family's bias current at 25C (1 pA, typical). The easiest way to reduce surface leakage is to use a guard ring around sensitive pins (or traces). The guard ring is biased at the same voltage as the sensitive pin. An example of this type of layout is illustrated in Figure 4-7. (c) 2008 Microchip Technology Inc.

The amplifier and feedback loops in this active voltage rectifier circuit eliminate the diode drop problem that exists in a passive voltage rectifier. This circuit behaves as a follower (the output follows the input) as long as the input signal is more positive than the reference voltage. If the input signal is more negative than the reference voltage, however, the circuit behaves as an inverting amplifier. Therefore, the output voltage will always be above the reference voltage, regardless of the input signal.

It saves one op amp over the typical Miller integrator plus inverting amplifier configuration. The phase accuracy of this integrator depends on the matching of the input and feedback resistor-capacitor time constants. RF makes this a lossy integrator (it has finite gain at DC), and makes this integrator stable by itself.

MCP6271/1R/2/3/4/5 4.9.3 CASCADED OP AMP APPLICATIONS R4 R3 R2 R1 The MCP6275 provides the flexibility of Low power mode for dual op amps in an 8-pin package. The MCP6275 eliminates the added cost and space in a battery powered application by using two single op amps with Chip Select (CS) lines or a 10-pin device with one CS line for both op amps. Since the two op amps are internally cascaded, this device cannot be used in circuits that require active or passive elements between the two op amps. However, there are several applications where this op amp configuration with a CS line becomes suitable. The circuits below show possible applications for this device. B A VIN MCP6275 VOUT CS FIGURE 4-11: Configuration. 4.9.3.3 Cascaded Gain Circuit 4.9.3.1 Load Isolation Difference Amplifier With the cascaded op amp configuration, op amp B can be used to isolate the load from op amp A. In applications where op amp A is driving capacitive or low resistive loads in the feedback loop (such as an integrator or filter circuit) the op amp may not have sufficient source current to drive the load. In this case, op amp B can be used as a buffer. Figure 4-12 shows op amp A configured as a difference amplifier with Chip Select. In this configuration, it is recommended that well matched resistors (e.g., 0.1%) be used to increase the Common Mode Rejection Ratio (CMRR). Op amp B can be used to provide additional gain and isolate the load from the difference amplifier.

Cascaded Gain Inverting Integrator with Active Compensation and Chip Select Figure 4-11 shows a cascaded gain circuit configuration with Chip Select. Op amps A and B are configured in a non-inverting amplifier configuration. In this configuration, it is important to note that the input offset voltage of op amp A is amplified by the gain of op amp A and B, as shown below: V OUT = V IN G A G B + V OSA G A G B + V OSB G B Where: GA GB VOSA VOSB = = = = op amp A gain op amp B gain op amp A input offset voltage op amp B input offset voltage Figure 4-13 uses an active compensator (op amp B) to compensate for the non-ideal op amp characteristics introduced at higher frequencies. This circuit uses op amp B as a unity gain buffer to isolate the integration capacitor C1 from op amp A and drives the capacitor with a low impedance source. Since both op amps are matched very well, they provide a high quality integrator. R1 VIN A MCP6275 C1 B VOUT Therefore, it is recommended that you set most of the gain with op amp A and use op amp B with relatively small gain (e.g., a unity gain buffer).

R1 and R2 are used to set the circuit gain. R3 is used to set the Q. To avoid gain peaking in the frequency response, Q needs to be low (lower values need to be selected for R3).
