SGM8634XS14 from SGMICRO, in a SOIC-14. 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 | Output of amplifier A, which provides rail-to-rail output swing into heavy loads. |
| 2 | -INA | input | Inverting input of amplifier A; the input common-mode voltage range includes ground and reaches -0.1V to +5.6V at VS = 5.5V. |
| 3 | +INA | input | Non-inverting input of amplifier A; the input common-mode voltage range includes ground and reaches -0.1V to +5.6V at VS = 5.5V. |
| 4 | +VS | power_in | Positive supply, operating from 2.5V to 5.5V (absolute maximum supply voltage is 6V); bypass with a 0.1µF ceramic capacitor close to the pin. |
| 5 | +INB | input | Non-inverting input of amplifier B; the input common-mode voltage range includes ground and reaches -0.1V to +5.6V at VS = 5.5V. |
| 6 | -INB | input | Inverting input of amplifier B; the input common-mode voltage range includes ground and reaches -0.1V to +5.6V at VS = 5.5V. |
| 7 | OUTB | output | Output of amplifier B, which provides rail-to-rail output swing into heavy loads. |
| 8 | OUTC | output | Output of amplifier C, which provides rail-to-rail output swing into heavy loads. |
| 9 | -INC | input | Inverting input of amplifier C; the input common-mode voltage range includes ground and reaches -0.1V to +5.6V at VS = 5.5V. |
| 10 | +INC | input | Non-inverting input of amplifier C; the input common-mode voltage range includes ground and reaches -0.1V to +5.6V at VS = 5.5V. |
| 11 | -VS | power_in | Negative supply; it is ground in single-supply operation, and for dual supplies (±1.25V to ±2.75V) it is bypassed to ground with its own 0.1µF capacitor. |
| 12 | +IND | input | Non-inverting input of amplifier D; the input common-mode voltage range includes ground and reaches -0.1V to +5.6V at VS = 5.5V. |
| 13 | -IND | input | Inverting input of amplifier D; the input common-mode voltage range includes ground and reaches -0.1V to +5.6V at VS = 5.5V. |
| 14 | OUTD | output | Output of amplifier D, which provides rail-to-rail output swing into heavy loads. |
