LM7332MA 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 Output of amplifier A, rail-to-rail with output short-circuit current above 100mA at VS = ±15V and stable with unlimited capacitive load.
2 IN- A input Inverting input of amplifier A, with input common-mode range extending 0.3V beyond the supply rails and differential input voltage limited to ±10V.
3 IN+ A input Non-inverting input of amplifier A, with input common-mode range extending 0.3V beyond the supply rails and differential input voltage limited to ±10V.
4 V- power_in Negative supply pin; total supply voltage V+ - V- is 2.5V to 32V recommended (35V absolute maximum).
5 IN+ B input Non-inverting input of amplifier B, with input common-mode range extending 0.3V beyond the supply rails and differential input voltage limited to ±10V.
6 IN- B input Inverting input of amplifier B, with input common-mode range extending 0.3V beyond the supply rails and differential input voltage limited to ±10V.
7 OUT B output Output of amplifier B, rail-to-rail with output short-circuit current above 100mA at VS = ±15V and stable with unlimited capacitive load.
8 V+ power_in Positive supply pin; total supply voltage V+ - V- is 2.5V to 32V recommended (35V absolute maximum), decoupled with about 0.01µF ceramic plus >4.7µF capacitor.
