# OPA2317M

**HGSEMI** · Precision OpAmps · SOP-8

OPA2317M from HGSEMI, in a SOP-8. 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 | OUTA | output | Channel A amplifier output with rail-to-rail swing, able to drive up to 30 mA output current (short-circuit limit 20 mA typical). |
| 2 | INA- | input | Channel A inverting input, 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. |
| 3 | INA+ | input | Channel A non-inverting input, 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 | VSS | power_in | Negative supply or ground; for dual-supply operation it is bypassed with a 0.1µF ceramic capacitor, with VDD to VSS limited to 7.5V absolute maximum. |
| 5 | INB+ | input | Channel B non-inverting input, 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. |
| 6 | INB- | input | Channel B inverting input, 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. |
| 7 | OUTB | output | Channel B amplifier output with rail-to-rail swing, able to drive up to 30 mA output current (short-circuit limit 20 mA typical). |
| 8 | VDD | power_in | Positive supply operating from 1.8V to 5.5V (7.5V absolute maximum), with a 0.1µF ceramic bypass capacitor placed close to the pin. |

## CAD (KiCad official)

- Symbol: `OPA2317M`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOP-8 (KiCad packages3D, STEP)
- 3D model files: `opa2317m-etched.step` / `opa2317m-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `opa2317m.step` / `opa2317m.glb` are the bare package body.
