GS8332-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 swing (typ. within 5 mV of supply rails with RL=100 kOhm, 20 mV with RL=10 kOhm). Short-circuit current limit ~20 mA typ. |
| 2 | INA- | input | Amplifier A inverting input. Rail-to-rail common-mode range (VSS-0.1 V to VDD+0.1 V). Input bias current typ. 20 pA @ 25 C. |
| 3 | INA+ | input | Amplifier A non-inverting input. Rail-to-rail common-mode range (VSS-0.1 V to VDD+0.1 V). Input bias current typ. 20 pA @ 25 C. |
| 4 | VSS | power_in | Negative supply / ground. For single-supply operation tie to GND; for dual-supply operation typ. -0.9 V to -2.75 V. Decouple to VDD with 0.1 uF ceramic close to the pin. |
| 5 | INB+ | input | Amplifier B non-inverting input. Rail-to-rail common-mode range (VSS-0.1 V to VDD+0.1 V). Input bias current typ. 20 pA @ 25 C. |
| 6 | INB- | input | Amplifier B inverting input. Rail-to-rail common-mode range (VSS-0.1 V to VDD+0.1 V). Input bias current typ. 20 pA @ 25 C. |
| 7 | OUTB | output | Amplifier B output. Rail-to-rail swing (typ. within 5 mV of supply rails with RL=100 kOhm, 20 mV with RL=10 kOhm). Short-circuit current limit ~20 mA typ. |
| 8 | VDD | power_in | Positive supply. 1.8 V to 5.5 V single-supply operating range (absolute max 7.5 V VDD-VSS). Bypass to VSS with a 0.1 uF ceramic close to the pin. |

Two STEP files. Same geometry, different body top:

|---|---|---|

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 593 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.
