OPA4340UA

UMW · Operational Amplifier · SOP-14

OPA4340UA from UMW, in a SOP-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 Output of channel A op-amp. Rail-to-rail output, swings within 1 mV of V+/V- rails with a 100 kΩ load.
2 -INA input Inverting (negative) input of channel A op-amp. Rail-to-rail input, common-mode range extends 500 mV beyond each supply rail.
3 +INA input Non-inverting (positive) input of channel A op-amp. Rail-to-rail input.
4 V+ power_in Positive (highest) power supply. Single-supply operation from 2.5 V up to 5.5 V (absolute-max supply span typically 7 V). Decouple with 0.1 µF near the pin.
5 +INB input Non-inverting (positive) input of channel B op-amp. Rail-to-rail input.
6 -INB input Inverting (negative) input of channel B op-amp.
7 OUTB output Output of channel B op-amp. Rail-to-rail output.
8 OUTC output Output of channel C op-amp. Rail-to-rail output.
9 -INC input Inverting (negative) input of channel C op-amp.
10 +INC input Non-inverting (positive) input of channel C op-amp.
11 V- power_in Negative (lowest) power supply. Tie to ground for single-supply operation, or to a negative rail for split-supply use.
12 +IND input Non-inverting (positive) input of channel D op-amp.
13 -IND input Inverting (negative) input of channel D op-amp.
14 OUTD output Output of channel D op-amp. Rail-to-rail output.

CAD (KiCad official)

  • Symbol: OPA4340UA
  • Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
  • 3D model: SOP-14 (KiCad packages3D, STEP)
  • 3D model files: opa4340ua-etched.step / opa4340ua-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); opa4340ua.step / opa4340ua.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
opa4340ua.step 195 KB You want the bare part, or you mark your own boards.
opa4340ua-etched.step 2.2 MB You want the part with OPA4340UA already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 560 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 (18 pp, sha256 e75e687924f6aa75, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
