High-Current, 10, SPST, CMOS Analog Switches
General Description
Maxim's MAX4655-MAX4658 are medium-voltage CMOS analog switches with low on-resistance of 10 max, specifically designed to handle large switch currents. With a switch capability of up to 400mA peak current and 300mA continuous current (MAX4655/ MAX4656), and up to 300mA peak current and 150mA continuous current (MAX4657/MAX4658), these parts can switch loads as low as 25. They can replace reed relays with a million times the speed and virtually unlimited number of lifetime cycles. Normal power consumption is only 3mW, whether the switch is on or off. These parts are TTL/CMOS compatible and will switch any voltage within its power-supply range. These are SPST (single-pole/single-throw) switches. The MAX4655/MAX4657 are normally closed (NC), while the MAX4656/MAX4658 are normally open (NO). The difference between the MAX4655/MAX4656 and the MAX4657/MAX4658 is in the power dissipation of their packages. Refer to the Absolute Maximum Ratings and the Electrical Characteristics. The MAX4655-MAX4658 power-supply range is from 4.5V to 20V for dual-supply operation and +9V to +40V for single-supply operation. These switches can operate from any combination of supplies, within a 40V V+ to V- range. They conduct equally well in either direction and can handle rail-to-rail analog signals. The offleakage current is only 1nA max at TA = +25C. They are available in 8-pin MAX(R), TDFN, and SO packages, with exposed paddle options for high-power applications.

Note 1: Signals on NC, NO, COM, or IN exceeding V+ or V- will be clamped by internal diodes. Limit forward diode current to maximum current rating.
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Detailed Description
The MAX4655-MAX4658 are single SPST CMOS analog switches. The CMOS switch construction provides rail-to-rail signal handling while consuming very little power. The switch is controlled by a TTL/CMOS level compatible digital input. The MAX4655/MAX4657 are normally closed switches, and the MAX4656/MAX4658 are normally open switches. These devices can be operated with either single power supplies or dual power supplies. Operation at up to 20V supplies allows users a wide switching dynamic range. Additionally, asymmetrical operation is possible to tailor performance to a particular application. These switches have been specifically designed to handle high switch currents, up to 400mA peak current and 300mA continuous currents. In order to do this, a new technique is used to drive the body of the output N-channel device. (Note: the basic switch between the input NC/NO terminal, and the output common terminal consists of an N-channel MOSFET and a P-channel MOSFET in parallel.) The standard method limits operation to approximately a 600mV drop across the switch. More than 600mV causes an increase in IdON leakage current (due to the turn-on of on-chip parasitic diodes) and an increase in V+ supply current. With the new sensing method, there is no limitation to the voltage drop across the switch. Current and voltage are limited only by the power dissipation rating of the package and the absolute maximum ratings of the switch. When the analog input to output voltage drop is approximately 7mV there is an increase in power supply current from typically 90A to 2mA within a 1mV to 7mV range, caused by the new sensing/driving circuitry.
Applications Information
Overvoltage Protection
Proper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maximum ratings, because stresses beyond the listed ratings can cause permanent damage to the devices. First, connect GND, followed by V+, V-, and the remaining pins. If power-supply sequencing is not possible, add two small signal diodes (D1, D2) in series with supply pins (Figure 1). Adding diodes reduces the analog signal range to one diode drop below V+ and one diode drop above V-, but does not affect the devices' low switch resistance and low leakage characteristics. Device operation is unchanged, and the difference between V+ and V- should not exceed 44V. The protection diode for the negative supply is not required when V- is connected to GND.
MAX4655-MAX4658
Off-Isolation at High Frequencies
In 50 systems, the high-frequency on-response of these parts extends from DC to above 100MHz, with a typical loss of -2dB. When the switch is turned off, however, it behaves like a capacitor, and off-isolation decreases with increasing frequency. This effect is more pronounced with higher source and load impedances. Above 5MHz, circuit board layout becomes critical. The graphs shown in the Typical Operating Characteristics were taken using a 50 source and load connected with BNC connectors.
