# GS8052-MR

**Gainsil** · Operational Amplifier · MSOP-8

GS8052-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 | Op-amp A output. Rail-to-rail output with ~0.12V swing from rail at RL=150Ω; drives up to 80mA min output current. |
| 2 | INA- | input | Op-amp A inverting input. Analog input voltage must remain within Vss-0.5V to VDD+0.5V; input bias current is typically 1pA. |
| 3 | INA+ | input | Op-amp A non-inverting input. Input common-mode voltage range is -0.2V to +3.8V (typ) on a 5V supply. |
| 4 | VSS | power_in | Negative supply rail (or ground for single-supply operation). Absolute max VDD-VSS is +7.5V; typical single-supply operation from +2.5V to +5.5V referenced to VSS=0V. |
| 5 | INB+ | input | Op-amp B non-inverting input. Input common-mode voltage range is -0.2V to +3.8V (typ) on a 5V supply. |
| 6 | INB- | input | Op-amp B inverting input. Analog input voltage must remain within Vss-0.5V to VDD+0.5V; input bias current is typically 1pA. |
| 7 | OUTB | output | Op-amp B output. Rail-to-rail output with ~0.12V swing from rail at RL=150Ω; drives up to 80mA min output current. |
| 8 | VDD | power_in | Positive supply rail. Operating range +2.5V to +5.5V (single-supply); absolute max +7.5V referenced to VSS. Quiescent current is 2.8mA per amplifier (typ). |

## CAD (KiCad official)

- Symbol: `GS8052-MR`
- Footprint: `Package_SO:MSOP-8_3x3mm_P0.65mm`
- 3D model: MSOP-8 (KiCad packages3D, STEP)
- 3D model files: `gs8052-mr-etched.step` / `gs8052-mr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `gs8052-mr.step` / `gs8052-mr.glb` are the bare package body.
