# OPA376AIDCKR

**Texas Instruments** · Precision OpAmps · SC-70-5

OPA376AIDCKR from Texas Instruments, in a SC-70-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | +IN | input | Non-inverting input of the op-amp. Rail-to-rail input range from V- to V+. |
| 2 | V- | power_in | Negative supply voltage. For single-supply operation tie to GND; for dual-supply operation connect to negative rail. Total supply range 2.2-5.5 V between V+ and V-. |
| 3 | -IN | input | Inverting input of the op-amp. Rail-to-rail input range from V- to V+. |
| 4 | OUT | output | Rail-to-rail amplifier output signal. Can swing within millivolts of both supply rails under light load. |
| 5 | V+ | power_in | Positive supply voltage. Operating range 2.2-5.5 V (with respect to V-). Bypass with a 0.1 uF ceramic capacitor close to the pin. |

## CAD (KiCad official)

- Symbol: `OPA376AIDCKR`
- Footprint: `Package_TO_SOT_SMD:SOT-353_SC-70-5`
- 3D model: SC-70-5 (KiCad packages3D, STEP)
- 3D model files: `opa376aidckr-etched.step` / `opa376aidckr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `opa376aidckr.step` / `opa376aidckr.glb` are the bare package body.
