OPA4348AIDR

Texas Instruments · Operational Amplifier · SOIC-14

OPA4348AIDR from Texas Instruments, in a SOIC-14. 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 OUT A output Output of op-amp channel A. Rail-to-rail output stage swings to within millivolts of V+ and V-.
2 -IN A input Inverting input of op-amp channel A. Rail-to-rail input common-mode range.
3 +IN A input Non-inverting input of op-amp channel A. Rail-to-rail input common-mode range.
4 V+ power_in Positive supply voltage. Single supply 2.5 V to 5.5 V or split ±1.25 V to ±2.75 V.
5 +IN B input Non-inverting input of op-amp channel B.
6 -IN B input Inverting input of op-amp channel B.
7 OUT B output Output of op-amp channel B.
8 OUT C output Output of op-amp channel C.
9 -IN C input Inverting input of op-amp channel C.
10 +IN C input Non-inverting input of op-amp channel C.
11 V- power_in Negative supply or ground. Tie to GND for single-supply operation.
12 +IN D input Non-inverting input of op-amp channel D.
13 -IN D input Inverting input of op-amp channel D.
14 OUT D output Output of op-amp channel D.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
opa4348aidr.step 195 KB You want the bare part, or you mark your own boards.
opa4348aidr-etched.step 2.5 MB You want the part with OPA4348AIDR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 636 faces against 237 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 (32 pp, sha256 998c84554552f1d1, 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).
