Pinout

Pin Name Type Function
1 OUT A output Output of amplifier A, which swings rail-to-rail and has an indefinite output short-circuit duration to GND.
2 -IN A input Inverting input of amplifier A, whose input voltage range is -0.1 V to +14 V at 16 V supply (-0.1 V to +3 V at 5 V) and whose input current should be limited to 10 mA or less when the input exceeds a supply rail by 0.3 V.
3 +IN A input Non-inverting input of amplifier A, whose input voltage range is -0.1 V to +14 V at 16 V supply (-0.1 V to +3 V at 5 V) and whose input current should be limited to 10 mA or less when the input exceeds a supply rail by 0.3 V.
4 V- power_in Negative power supply, used with single supply operation from 5 V to 16 V or dual supply of ±2.5 V to ±8 V.
5 +IN B input Non-inverting input of amplifier B, whose input voltage range is -0.1 V to +14 V at 16 V supply (-0.1 V to +3 V at 5 V) and whose input current should be limited to 10 mA or less when the input exceeds a supply rail by 0.3 V.
6 -IN B input Inverting input of amplifier B, whose input voltage range is -0.1 V to +14 V at 16 V supply (-0.1 V to +3 V at 5 V) and whose input current should be limited to 10 mA or less when the input exceeds a supply rail by 0.3 V.
7 OUT B output Output of amplifier B, which swings rail-to-rail and has an indefinite output short-circuit duration to GND.
8 V+ power_in Positive power supply, with a 16 V absolute maximum supply voltage and operation from 5 V to 16 V single supply or ±2.5 V to ±8 V dual supply.
