GS8552-SR from Gainsil, in a SOIC-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; can swing within a few mV of VSS/VDD under light load (>100 kΩ) and within ~60 mV at 10 kΩ. Short-circuit current ~60 mA. |
| 2 | INA- | input | Amplifier A inverting input. Rail-to-rail common-mode range from VSS-0.1 V to VDD+0.1 V. Input bias current 20 pA (typ). |
| 3 | INA+ | input | Amplifier A non-inverting input. Rail-to-rail common-mode range from VSS-0.1 V to VDD+0.1 V. Input bias current 20 pA (typ). |
| 4 | VSS | power_in | Negative supply / ground. In single-supply mode connect to GND; in dual-supply mode connect to the negative rail. Total supply (VDD-VSS) range 1.8 V to 5.5 V (7.5 V abs max). |
| 5 | INB+ | input | Amplifier B non-inverting input. Rail-to-rail common-mode range from VSS-0.1 V to VDD+0.1 V. Input bias current 20 pA (typ). |
| 6 | INB- | input | Amplifier B inverting input. Rail-to-rail common-mode range from VSS-0.1 V to VDD+0.1 V. Input bias current 20 pA (typ). |
| 7 | OUTB | output | Amplifier B output. Rail-to-rail output stage; can swing within a few mV of VSS/VDD under light load (>100 kΩ) and within ~60 mV at 10 kΩ. Short-circuit current ~60 mA. |
| 8 | VDD | power_in | Positive supply. Single-supply 1.8 V to 5.5 V (7.5 V abs max). Bypass with a 0.1 µF ceramic to VSS/GND close to the pin. |

Two STEP files. Same geometry, different body top:
| File | Size | Use it when |
|---|---|---|
gs8552-sr.step |
122 KB | You want the bare part, or you mark your own boards. |

2.4 MB | You want the part with GS8552-SR already on it. |
The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 565 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.
