Description
The FAN4174 (single) and FAN4274 (dual) are ultra-low cost voltage feedback amplifiers with CMOS inputs that consume only 200A of supply current per amplifier, while providing 33mA of output short-circuit current. These amplifiers are designed to operate from 2.5V to 5V supplies. The common mode voltage range extends beyond the negative and positive rails. The FAN4174 and FAN4274 are designed on a CMOS process and provide 3.7MHz of bandwidth and 3V/s of slew rate at a supply voltage of 5V. The combination of low power, rail-to-rail performance, low-voltage operation, and tiny package options make this amplifier family well suited for use in many general-purpose and battery-powered applications.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Functional operation under any of these conditions is NOT implied. Performance and reliability are guaranteed only if operating conditions are not exceeded.

Application Information
General Description
The FAN4174 amplifier includes single-supply, generalpurpose, voltage-feedback amplifiers, fabricated on a bi-CMOS process. The family features a rail-to-rail input and output and is unity gain stable. The typical noninverting circuit schematic is shown in Figure 22.
Overdrive Recovery
Overdrive of an amplifier occurs when the output and/or input ranges are exceeded. The recovery time varies based on whether the input or output is overdriven and by how much the range is exceeded. The FAN4174 typically recovers in less than 500ns from an overdrive condition. Figure 24 shows the FAN4174 amplifier in an overdriven condition.
Figure 22. Typical Non-inverting Configuration
Figure 24. Overdrive Recovery
Input Common Mode Voltage
The common mode input range extends to 300mV below ground and to 100mV above VS in single supply operation. Exceeding these values does not cause phase reversal; however, if the input voltage exceeds the rails by more than 0.5V, the input ESD devices begin to conduct. The output stays at the rail during this overdrive condition. If the absolute maximum input VIN (700mV beyond either rail) is exceeded, externally limit the input current to 5mA, as shown in Figure 23.
Driving Capacitive Loads
Figure 10 illustrates the response of the FAN4174 amplifier family. A small series resistance (RS) at the output of the amplifier, illustrated in Figure 25, improves stability and settling performance. RS values in Figure 10 were chosen to achieve maximum bandwidth with less than 2dB of peaking. For maximum flatness, use a larger RS. Capacitive loads larger than 500pF require the use of RS.
Figure 23. Circuit for Input Current Protection
Power Dissipation
The maximum internal power dissipation allowed is directly related to the maximum junction temperature. If the maximum junction temperature exceeds 150C, performance degradation occurs. If the maximum junction temperature exceeds 150C for an extended time, device failure may occur.
Figure 25. Typical Topology for Driving a Capacitive Load Driving a capacitive load introduces phase-lag into the output signal, which reduces phase margin in the amplifier. The unity gain follower is the most sensitive configuration. In a unity gain follower configuration, the FAN4174 amplifier family requires a 300 series resistor to drive a 100pF load.

Layout Considerations
General layout and supply bypassing play major roles in high-frequency performance. Fairchild evaluation boards help guide high-frequency layout and aid in device testing and characterization. Follow the steps below as a basis for high-frequency layout: 1. 2. 3. 4. Include 6.8F and 0.01F ceramic capacitors. Place the 6.8F capacitor within 0.75 inches of the power pin. Place the 0.01F capacitor within 0.1 inches of the power pin. Remove the ground plane under and around the part, especially near the input and output pins, to reduce parasitic capacitance. trace lengths to reduce series
Minimize all inductances.
Refer to the evaluation board layouts shown in Figures 28-31 for more information. When evaluating only one channel, complete the following on the unused channel: 1. 2. Ground the non-inverting input. Short the output to the inverting input. Figure 26. FAN4174 Evaluation Board Schematic (KEV002/KEB011)
