SGMICRO · Operational Amplifier · SOIC-8-150mil
SGM722XS from SGMICRO, in a SOIC-8-150mil. 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; rail-to-rail output swing into heavy loads. |
| 2 | -INA | input | Inverting input of amplifier A; input common-mode range includes ground, with -0.1V to +5.6V specified at VS = 5.5V. |
| 3 | +INA | input | Non-inverting input of amplifier A; input common-mode range includes ground, with -0.1V to +5.6V specified at VS = 5.5V. |
| 4 | -VS | power_in | Negative supply rail; in single-supply operation this is ground, and the operating supply range is 2.1V to 5.5V (+VS to -VS, 7V absolute maximum). |
| 5 | +INB | input | Non-inverting input of amplifier B; input common-mode range includes ground, with -0.1V to +5.6V specified at VS = 5.5V. |
| 6 | -INB | input | Inverting input of amplifier B; input common-mode range includes ground, with -0.1V to +5.6V specified at VS = 5.5V. |
| 7 | OUTB | output | Output of amplifier B; rail-to-rail output swing into heavy loads. |
| 8 | +VS | power_in | Positive supply rail; operating range 2.1V to 5.5V, bypass with 0.1µF ceramic capacitor placed close to the pin. |
