GS8552-MR from Gainsil, in a MSOP-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 | Output of amplifier A. Rail-to-rail output, capable of swinging within ~5mV of the supply rails with light loads (>100kΩ) and 60mV with 10kΩ. Short-circuit current typically 60mA. |
| 2 | INA- | input | Inverting input of amplifier A. Rail-to-rail input, allowed common-mode range VSS-0.1V to VDD+0.1V. Input bias current typ 20pA. |
| 3 | INA+ | input | Non-inverting input of amplifier A. Rail-to-rail input, allowed common-mode range VSS-0.1V to VDD+0.1V. Input bias current typ 20pA. |
| 4 | VSS | power_in | Negative supply / ground. Single-supply operation ties this to GND; dual-supply operation accepts ±0.9V to ±2.75V. Absolute max VDD-VSS = 7.5V. Bypass to ground with a 0.1µF ceramic capacitor. |
| 5 | INB+ | input | Non-inverting input of amplifier B. Rail-to-rail input, allowed common-mode range VSS-0.1V to VDD+0.1V. Input bias current typ 20pA. |
| 6 | INB- | input | Inverting input of amplifier B. Rail-to-rail input, allowed common-mode range VSS-0.1V to VDD+0.1V. Input bias current typ 20pA. |
| 7 | OUTB | output | Output of amplifier B. Rail-to-rail output, capable of swinging within ~5mV of the supply rails with light loads (>100kΩ) and 60mV with 10kΩ. Short-circuit current typically 60mA. |
| 8 | VDD | power_in | Positive supply. Single-supply operation from +1.8V to +5.5V (absolute max VDD-VSS = 7.5V). Quiescent current typ 180µA per amplifier (360µA total). Bypass to VSS with a 0.1µF ceramic capacitor placed close to the pin. |

Two STEP files. Same geometry, different body top:
| File | Size | Use it when |
|---|---|---|
gs8552-mr.step |
123 KB | You want the bare part, or you mark your own boards. |
gs8552-mr-etched.step |
2.2 MB | You want the part with GS8552-MR already on it. |
The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 535 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.
