OPA376AIDR

Texas Instruments · Precision OpAmps · SOIC-8

OPA376AIDR from Texas Instruments, in a SOIC-8. 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 NC unconnected No internal connection. May be left floating or tied to ground.
2 -IN input Inverting input of the operational amplifier. Rail-to-rail input range from V- to V+.
3 +IN input Non-inverting input of the operational amplifier. Rail-to-rail input range from V- to V+.
4 V- power_in Negative supply voltage rail. For single-supply operation connect to GND; for dual-supply operation connect to the negative rail. Total V+ to V- supply must be 2.2 V to 5.5 V.
5 NC unconnected No internal connection. May be left floating or tied to ground.
6 OUT output Operational amplifier output. Rail-to-rail output swings within millivolts of both supply rails under light loads.
7 V+ power_in Positive supply voltage rail. Total V+ to V- supply must be between 2.2 V and 5.5 V. Bypass with a 100 nF ceramic capacitor to V- close to the pin.
8 NC unconnected No internal connection. May be left floating or tied to ground.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
opa376aidr.step 122 KB You want the bare part, or you mark your own boards.
opa376aidr-etched.step 2.0 MB You want the part with OPA376AIDR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 496 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (46 pp, sha256 98ab1f4e86c825b5, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
