GS358-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 stage, can swing to within ~5mV of the supply rails at RL >= 100kOhm. Typical source/sink current ~84mA/75mA into 10Ohm to VS/2. |
| 2 | INA- | input | Inverting input of amplifier A. Rail-to-rail CMOS input; common-mode range extends from VSS-0.1V to VDD+0.1V. Input bias current ~1pA typical. |
| 3 | INA+ | input | Non-inverting input of amplifier A. Rail-to-rail CMOS input; common-mode range VSS-0.1V to VDD+0.1V. Input bias current ~1pA typical; input offset voltage 3.5mV max at 25C. |
| 4 | VSS | power_in | Negative supply rail (or ground in single-supply operation). Absolute maximum VDD-VSS = 7.5V; operating supply 2.1V to 5.5V single-supply, or +/-1.05V to +/-2.75V dual-supply. Bypass with 0.1uF ceramic to VDD close to the pin. |
| 5 | INB+ | input | Non-inverting input of amplifier B. Rail-to-rail CMOS input; common-mode range VSS-0.1V to VDD+0.1V. Input bias current ~1pA typical. |
| 6 | INB- | input | Inverting input of amplifier B. Rail-to-rail CMOS input; common-mode range VSS-0.1V to VDD+0.1V. Input bias current ~1pA typical. |
| 7 | OUTB | output | Output of amplifier B. Rail-to-rail output stage, swings to within ~5mV of the supply rails at light loads. Typical source/sink current ~84mA/75mA into 10Ohm to VS/2. |
| 8 | VDD | power_in | Positive supply rail. Operating range 2.1V to 5.5V single-supply; absolute maximum VDD-VSS = 7.5V. Bypass with 0.1uF ceramic close to the pin. |

Two STEP files. Same geometry, different body top:
| File | Size | Use it when |
|---|---|---|
gs358-mr.step |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 504 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.
