Pinout

Pin Name Type Function
1 NC unconnected No connect pin (marked NC in the pin configuration figure); it is not connected internally.
2 -IN input Inverting input; the absolute maximum differential input voltage is ±0.7 V.
3 +IN input Non-inverting input; the input voltage range is ±2.5 V with ±5 V supplies and ±12 V with ±15 V supplies.
4 V- power_in Negative supply; the part operates from dual supplies of ±5 V to ±15 V, with a 36 V absolute maximum supply voltage.
5 NC unconnected No connect pin (marked NC in the pin configuration figure); it is not connected internally.
6 OUT output Amplifier output; it sources or sinks up to ±10 mA at ±5 V supply and ±20 mA at ±15 V supply, and the output short-circuit duration is indefinite.
7 V+ power_in Positive supply; the part operates from dual supplies of ±5 V to ±15 V, with a 36 V absolute maximum supply voltage.
8 NC unconnected No connect pin (marked NC in the pin configuration figure); it is not connected internally.
