**Hangzhou Ruimeng Tech** · Precision OpAmps · SOT-23-5

MS8605 from Hangzhou Ruimeng Tech, in a SOT-23-5. 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 | OUT | output | Op-amp output. Rail-to-rail output; VOH ≈ 4.99 V @ IL=1 mA (VCC=5 V), short-circuit current ±80 mA, closed-loop output impedance 11 Ω @ 1 MHz. |
| 2 | GND | power_in | Ground / negative supply reference. Connect to system ground (0 V). |
| 3 | +IN | input | Non-inverting input. Rail-to-rail input range 0 V to VCC; input bias current 0.2 pA typ; differential input voltage ±6 V max. |
| 4 | -IN | input | Inverting input. Rail-to-rail input range 0 V to VCC; input bias current 0.2 pA typ. |
| 5 | VCC | power_in | Positive supply. Operating range 2.7 V to 5.5 V, absolute max 6 V. Quiescent current 1.5 mA typ (1.8 mA max @ full temp). |

## CAD (KiCad official)

- Symbol: `MS8605`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `ms8605-etched.step` / `ms8605-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ms8605.step` / `ms8605.glb` are the bare package body.
