OPA2320AID from Texas Instruments, 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 OUT A output Channel A output; typical swing is 10 mV from each rail at RL = 10 kΩ and TA = 25°C.
2 -IN A input Channel A inverting input; the common-mode input range is (V-) - 0.1 V to (V+) + 0.1 V.
3 +IN A input Channel A non-inverting input; the common-mode input range is (V-) - 0.1 V to (V+) + 0.1 V.
4 V- power_in Negative supply (lowest potential); the total supply is 1.8 V to 5.5 V, and the absolute maximum VS is 6 V.
5 +IN B input Channel B non-inverting input; the common-mode input range is (V-) - 0.1 V to (V+) + 0.1 V.
6 -IN B input Channel B inverting input; the common-mode input range is (V-) - 0.1 V to (V+) + 0.1 V.
7 OUT B output Channel B output; typical swing is 10 mV from each rail at RL = 10 kΩ and TA = 25°C.
8 V+ power_in Positive supply (highest potential); the total supply is 1.8 V to 5.5 V, and the absolute maximum VS is 6 V.
