GS6552-SR from Gainsil, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Amplifier A output. Rail-to-rail output stage; typical short-circuit limit 60mA, output current 65mA. |
| 2 | INA- | input | Amplifier A inverting input. Rail-to-rail input range extending from VSS-0.1V to VDD+0.1V; typical input bias current 20pA. |
| 3 | INA+ | input | Amplifier A non-inverting input. Rail-to-rail input range extending from VSS-0.1V to VDD+0.1V; typical input bias current 20pA. |
| 4 | VSS | power_in | Negative supply / ground. Single-supply operation ties this to GND; dual-supply operation uses ±0.9V to ±2.75V. Bypass with 0.1µF to ground. |
| 5 | INB+ | input | Amplifier B non-inverting input. Rail-to-rail input range extending from VSS-0.1V to VDD+0.1V; typical input bias current 20pA. |
| 6 | INB- | input | Amplifier B inverting input. Rail-to-rail input range extending from VSS-0.1V to VDD+0.1V; typical input bias current 20pA. |
| 7 | OUTB | output | Amplifier B output. Rail-to-rail output stage; typical short-circuit limit 60mA, output current 65mA. |
| 8 | VDD | power_in | Positive supply. Single-supply range 1.8V to 5.5V (absolute max 7.5V VDD-to-VSS). Bypass with 0.1µF ceramic close to the pin. |

Two STEP files. Same geometry, different body top:
| File | Size | Use it when |
|---|---|---|
gs6552-sr.step |
122 KB | You want the bare part, or you mark your own boards. |
gs6552-sr-etched.step |
2.3 MB | You want the part with GS6552-SR already on it. |
The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 550 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
