# OPA376AID

**Texas Instruments** · Operational Amplifier · SOIC-8

OPA376AID from Texas Instruments, in a SOIC-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 | NC | unconnected | No internal connection; the datasheet marks this pin NC (no internal connection) in the 8-pin SOIC pinout. |
| 2 | -IN | input | Inverting input signal; signal input pins are diode-clamped to the supply rails, and signals swinging more than 0.5 V beyond the rails should be current limited to 10 mA or less. |
| 3 | +IN | input | Non-inverting input signal; signal input pins are diode-clamped to the supply rails, and signals swinging more than 0.5 V beyond the rails should be current limited to 10 mA or less. |
| 4 | V- | power_in | Negative supply voltage; the supply span (V+) - (V-) must be between 2.2 V and 5.5 V. |
| 5 | NC | unconnected | No internal connection; the datasheet marks this pin NC (no internal connection) in the 8-pin SOIC pinout. |
| 6 | OUT | output | Amplifier output signal; output short-circuit to ground is specified as continuous (one amplifier per package). |
| 7 | V+ | power_in | Positive supply voltage; the supply span (V+) - (V-) must be between 2.2 V and 5.5 V. |
| 8 | NC | unconnected | No internal connection; the datasheet marks this pin NC (no internal connection) in the 8-pin SOIC pinout. |

## CAD (KiCad official)

- Symbol: `OPA376AID`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `opa376aid-etched.step` / `opa376aid-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `opa376aid.step` / `opa376aid.glb` are the bare package body.
