SGM8632XS from SGMICRO, 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 | OUTA | output | Channel A output, which provides rail-to-rail output swing into heavy loads. |
| 2 | -INA | input | Channel A inverting input; the input common-mode voltage range includes ground and extends to +5.6V at VS = 5.5V (-0.1V to +5.6V). |
| 3 | +INA | input | Channel A non-inverting input; the input common-mode voltage range includes ground and extends to +5.6V at VS = 5.5V (-0.1V to +5.6V). |
| 4 | -VS | power_in | Negative supply rail, tied to ground for single-supply operation; the device operates from +2V to +5.5V single supply or ±1V to ±2.75V dual supply. |
| 5 | +INB | input | Channel B non-inverting input; the input common-mode voltage range includes ground and extends to +5.6V at VS = 5.5V (-0.1V to +5.6V). |
| 6 | -INB | input | Channel B inverting input; the input common-mode voltage range includes ground and extends to +5.6V at VS = 5.5V (-0.1V to +5.6V). |
| 7 | OUTB | output | Channel B output, which provides rail-to-rail output swing into heavy loads. |
| 8 | +VS | power_in | Positive supply rail, operating from +2V to +5.5V with a 6V absolute maximum supply voltage; bypass with a 0.1µF ceramic capacitor placed close to the pin. |
