2 -In input Inverting input terminal with maximum signal input current of 20 mA.
3 +In input Non-inverting input terminal with maximum signal input current of 20 mA.
4 V- power_in Negative power supply rail.
5 NC unconnected Not internally connected and may be left floating.
6 Output output Output signal terminal.
7 V+ power_in Positive power supply rail.
8 Offset Trim input Input offset voltage adjustment pin that should be left floating if unused.
