**HGSEMI** · Precision OpAmps · SOT-23-5

OPA376M5 from HGSEMI, 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 | Amplifier output. Rail-to-rail; can source/sink typ. 30mA, short-circuit limit 43mA into 10Ω. |
| 2 | VSS | power_in | Negative supply / ground. Single-supply operation from 1.8V to 5.5V referenced to VSS; VDD−VSS absolute max +7.5V. |
| 3 | IN+ | input | Non-inverting analog input. Rail-to-rail input range VSS−0.5V to VDD+0.5V (abs max); 20pA typical input bias current. |
| 4 | IN- | input | Inverting analog input. Rail-to-rail input range VSS−0.5V to VDD+0.5V (abs max); 20pA typical input bias current. |
| 5 | VDD | power_in | Positive supply. 1.8V to 5.5V single-supply; absolute max VDD−VSS = 7.5V. Decouple with 100nF close to pin. |

## CAD (KiCad official)

- Symbol: `OPA376M5`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `opa376m5-etched.step` / `opa376m5-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `opa376m5.step` / `opa376m5.glb` are the bare package body.
