**HGSEMI** · Operational Amplifier · SOT23-5

HGV8331M5 from HGSEMI, in a SOT23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | output | Amplifier output, rail-to-rail swing. |
| 2 | VSS | power_in | Negative supply (ground in single-supply operation); supply range VDD to VSS is 1.8V to 5.5V, absolute max 7.5V. |
| 3 | IN+ | input | Non-inverting input, rail-to-rail, common-mode range VSS-0.1V to VDD+0.1V. |
| 4 | IN- | input | Inverting input, rail-to-rail, common-mode range VSS-0.1V to VDD+0.1V. |
| 5 | VDD | power_in | Positive supply, 1.8V to 5.5V single supply; bypass with a 0.1uF ceramic capacitor close to the pin. |
