OPA4348AIPWR

UMW · Operational Amplifier · TSSOP-14

OPA4348AIPWR from UMW, in a TSSOP-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 OUTA output Op-amp A output. Rail-to-rail output; short-circuit current typ. ±10mA.
2 -INA input Op-amp A inverting input. Rail-to-rail input; input bias typ. 0.5pA.
3 +INA input Op-amp A non-inverting input. Rail-to-rail input; input bias typ. 0.5pA.
4 V+ power_in Positive supply rail. Single-supply +2.1V to +5.5V (7.5V abs. max). Bypass with 0.1µF to V-.
5 +INB input Op-amp B non-inverting input. Rail-to-rail input.
6 -INB input Op-amp B inverting input. Rail-to-rail input.

Ordering variants

Same part, different packaging or reel option.

  • OPA4348AIPWR

CAD (KiCad official)

  • Symbol: OPA4348AIPWR
  • Footprint: Package_SO:TSSOP-14_4.4x5mm_P0.65mm
  • 3D model: TSSOP-14 (KiCad packages3D, STEP)
  • 3D model files: opa4348aipwr-etched.step / opa4348aipwr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); opa4348aipwr.step / opa4348aipwr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
opa4348aipwr.step 194 KB You want the bare part, or you mark your own boards.
opa4348aipwr-etched.step 2.6 MB You want the part with OPA4348AIPWR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 669 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: UMW datasheet (15 pp, sha256 6586421a3d8314ed, retrieved 2026-08-17, tier: lcsc)
  • 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).
