INA102ASOIC8 from analogysemi, in a SOIC-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 RG passive Connect a resistor between the two RG pins (1 and 8) to set gain, using RG = 49.4kΩ/(G−1); for G = 1 the RG pins are left unconnected.
2 -IN input Signal negative input, whose input voltage range is −VS + 0.1 V to +VS − 2 V for the INA102.
3 +IN input Signal positive input, whose input voltage range is −VS + 0.1 V to +VS − 2 V for the INA102.
4 -VS power_in Negative power supply; the INA102 split-supply operating range is ±2 V to ±19 V.
5 REF input Output reference voltage input that defines the zero-output level, with an allowable range of 2 V within the supply voltages and a low-impedance connection recommended for best CMR.
6 OUTPUT output Amplifier output, referred to the REF pin, with a specified short-circuit current of ±17 mA over temperature.
7 +VS power_in Positive power supply; the INA102 split-supply operating range is ±2 V to ±19 V.
8 RG passive Connect a resistor between the two RG pins (1 and 8) to set gain, using RG = 49.4kΩ/(G−1); for G = 1 the RG pins are left unconnected.
