Pinout

Pin Name Type Function
1 NC unconnected No connect pin, marked NC in the datasheet pin figure and not assigned a function.
2 -IN input Inverting input; the datasheet specifies an input voltage range of 0 V to 5 V at VS = 5 V and 0 V to 2.7 V at VS = 2.7 V, with absolute maximum input voltage of VSS − 0.3 V to VDD + 0.3 V.
3 +IN input Non-inverting input; the datasheet specifies an input voltage range of 0 V to 5 V at VS = 5 V and 0 V to 2.7 V at VS = 2.7 V, with absolute maximum input voltage of VSS − 0.3 V to VDD + 0.3 V.
4 V- power_in Negative supply; the part is fully specified for single-supply operation from 2.7 V to 5.0 V or dual supply of ±1.35 V to ±2.5 V, with absolute maximum supply voltage of +6 V.
5 NC unconnected No connect pin, marked NC in the datasheet pin figure and not assigned a function.
6 OUT output Amplifier output; the datasheet gives a short-circuit limit (ISC) of ±25 mA at VS = 5 V and ±8 mA at VS = 2.7 V.
7 V+ power_in Positive supply; the part is fully specified for single-supply operation from 2.7 V to 5.0 V, with absolute maximum supply voltage of +6 V.
8 NC unconnected No connect pin, marked NC in the datasheet pin figure and not assigned a function.
