GS8548-SR from Gainsil, in a SOP-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 amplifier output, rail-to-rail. |
| 2 | INA- | input | Channel A inverting input; input range extends 100mV beyond supply rails (VSS-0.1V to VDD+0.1V). |
| 3 | INA+ | input | Channel A non-inverting input; input range extends 100mV beyond supply rails (VSS-0.1V to VDD+0.1V). |
| 4 | VSS | power_in | Negative supply or ground; for dual-supply operation bypass to ground with a 0.1µF ceramic capacitor. |
| 5 | INB+ | input | Channel B non-inverting input; input range extends 100mV beyond supply rails (VSS-0.1V to VDD+0.1V). |
| 6 | INB- | input | Channel B inverting input; input range extends 100mV beyond supply rails (VSS-0.1V to VDD+0.1V). |
| 7 | OUTB | output | Channel B amplifier output, rail-to-rail. |
| 8 | VDD | power_in | Positive supply, 2.2V to 5.5V single supply (absolute max 7.5V VDD to VSS); bypass with a 0.1µF ceramic capacitor close to the pin. |
