Gainsil · Operational Amplifier · SOP-8
GS2904-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 | Output of amplifier A, with output swing from 0V to Vcc-1.5V and about 40mA source/sink current. |
| 2 | INA- | input | Inverting input of amplifier A, with input common-mode range including ground (-0.1V to VCC-1.5V). |
| 3 | INA+ | input | Non-inverting input of amplifier A, with input common-mode range including ground (-0.1V to VCC-1.5V). |
| 4 | VSS | power_in | Negative supply or ground for single-supply operation, in dual-supply operation down to -18V. |
| 5 | INB+ | input | Non-inverting input of amplifier B, with input common-mode range including ground (-0.1V to VCC-1.5V). |
| 6 | INB- | input | Inverting input of amplifier B, with input common-mode range including ground (-0.1V to VCC-1.5V). |
| 7 | OUTB | output | Output of amplifier B, with output swing from 0V to Vcc-1.5V and about 40mA source/sink current. |
| 8 | VDD | power_in | Positive supply, operating from +3V to +36V single supply (up to +18V in dual-supply operation). |
