**HGSEMI** · Operational Amplifier · SOP-8

OPA2348M 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 | Out A | output | Amplifier A output, rail-to-rail, with 10mA typical short-circuit current. |
| 2 | -In A | input | Amplifier A inverting input, common-mode range (V-)-0.2V to (V+)+0.2V with 0.5pA typical bias current. |
| 3 | +In A | input | Amplifier A non-inverting input, common-mode range (V-)-0.2V to (V+)+0.2V with 0.5pA typical bias current. |
| 4 | V- | power_in | Negative supply (ground in single-supply use); supply range 2.1V to 5.5V total, 7.5V absolute maximum. |
| 5 | +In B | input | Amplifier B non-inverting input, common-mode range (V-)-0.2V to (V+)+0.2V with 0.5pA typical bias current. |
| 6 | -In B | input | Amplifier B inverting input, common-mode range (V-)-0.2V to (V+)+0.2V with 0.5pA typical bias current. |
| 7 | Out B | output | Amplifier B output, rail-to-rail, with 10mA typical short-circuit current. |
| 8 | V+ | power_in | Positive supply, 2.1V to 5.5V operating (2.5V to 5.5V specified), 7.5V absolute maximum, bypass with 0.01µF ceramic capacitor. |

## CAD (KiCad official)

- Symbol: `OPA2348M`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOP-8 (KiCad packages3D, STEP)
- 3D model files: `opa2348m-etched.step` / `opa2348m-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `opa2348m.step` / `opa2348m.glb` are the bare package body.
