SGM8249-2XS8G 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 | Output of amplifier A, which provides rail-to-rail output operation. |
| 2 | -INA | input | Inverting input of amplifier A; the input voltage range is -VS to (+VS) + 0.1V per the absolute maximum ratings. |
| 3 | +INA | input | Non-inverting input of amplifier A; the common-mode input voltage range is (-VS) to (+VS) - 1.5V. |
| 4 | -VS | power_in | Negative power supply; operation is 4.5V to 36V single supply or ±2.25V to ±18V dual supplies. |
| 5 | +INB | input | Non-inverting input of amplifier B; the common-mode input voltage range is (-VS) to (+VS) - 1.5V. |
| 6 | -INB | input | Inverting input of amplifier B; the input voltage range is -VS to (+VS) + 0.1V per the absolute maximum ratings. |
| 7 | OUTB | output | Output of amplifier B, which provides rail-to-rail output operation. |
| 8 | +VS | power_in | Positive power supply; the absolute maximum supply voltage is 40V. |
