LT1637CS8#TRPBF from Analog Devices, in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NULL passive Offset null pin: a 10k potentiometer between pins 1 and 8 with its wiper to V- nulls the input offset, with a null range of at least ±3mV.
2 -IN input Inverting input, protected against excursions up to 22V below V- by an internal 1.3k series resistor and a diode to the negative supply, with a maximum differential input voltage of 44V.
3 +IN input Non-inverting input, with an input voltage range of 0V to 44V and an input that operates up to 44V above V- regardless of V+.
4 V- power_in Negative supply pin; the device is protected against reverse battery voltages up to 25V.
5 SHDN input Shutdown pin that can be taken up to 32V above V-; bringing it 1.2V above V- shuts the amplifier down to about 3µA supply current, and any pin current below V- must be limited to less than 10mA with an external resistor.
6 OUT output Amplifier output with rail-to-rail swing that drives 25mA minimum; it is unity-gain stable into capacitive loads up to 200pF, and up to 4700pF with a 0.22µF and 150Ω compensation network.
7 V+ power_in Positive supply pin; the total supply voltage (V+ to V-) is specified from 2.7V minimum to 44V maximum and should be bypassed with about 0.01µF within an inch of the pin.
8 NULL passive Offset null pin paired with pin 1 for the external 10k potentiometer nulling network, with its wiper to V-.
