OPA314AIDCKR

Texas Instruments · Operational Amplifier · SC-70-5

OPA314AIDCKR 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 Noninverting input of the op-amp. Rail-to-rail input stage with very low bias current (0.2pA typical).
2 V- power_in Negative (lowest) supply. Ground for single-supply operation, or negative rail for dual-supply operation. Supply range 1.8V to 5.5V total (V+ − V−).
3 -IN input Inverting input of the op-amp. Rail-to-rail input stage with very low bias current (0.2pA typical).
4 OUT output Rail-to-rail output of the op-amp. Drives loads to within millivolts of either supply rail.
5 V+ power_in Positive (highest) supply. 1.8V to 5.5V single supply, or up to ±2.75V dual supply. Bypass to V− with a 0.1µF ceramic capacitor close to the pin.

CAD (KiCad official)

  • Symbol: OPA314AIDCKR
  • Footprint: Package_TO_SOT_SMD:SOT-353_SC-70-5
  • 3D model: SC-70-5 (KiCad packages3D, STEP)
  • 3D model files: opa314aidckr-etched.step / opa314aidckr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); opa314aidckr.step / opa314aidckr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
opa314aidckr.step 87 KB You want the bare part, or you mark your own boards.
opa314aidckr-etched.step 2.0 MB You want the part with OPA314AIDCKR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 509 faces against 102 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 (49 pp, sha256 2968786e00b8c356, retrieved 2026-08-17, tier: manufacturer)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • 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).
