# OPA317M5

**HGSEMI** · Precision Op Amps · SOT-23-5

OPA317M5 from HGSEMI, in a SOT-23-5. 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 with rail-to-rail swing, typically within 5mV of the supply rail at loads above 100kΩ and rated for 30mA output current. |
| 2 | VSS | power_in | Negative supply (ground in single-supply operation); the input common-mode range extends from VSS-0.1V and the supply is bypassed with a 0.1µF ceramic capacitor in dual-supply operation. |
| 3 | IN+ | input | Non-inverting input, rail-to-rail with a common-mode range of VSS-0.1V to VDD+0.1V and an absolute maximum of VSS-0.5V to VDD+0.5V. |
| 4 | IN- | input | Inverting input, rail-to-rail with a common-mode range of VSS-0.1V to VDD+0.1V and an absolute maximum of VSS-0.5V to VDD+0.5V. |
| 5 | VDD | power_in | Positive supply for 1.8V to 5.5V single-supply operation (absolute maximum 7.5V VDD to VSS), bypassed with a 0.1µF ceramic capacitor placed close to the pin. |
