OPA391DCKR

Texas Instruments · Operational Amplifier · SC-70-5

OPA391DCKR 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 operational amplifier. Common-mode input range extends 100mV beyond each supply rail; VCM = (V-)-0.1V to (V+)+0.1V.
2 V- power_in Negative (lowest) power supply. Single-supply operation 1.7V to 5.5V referenced from V+ to V-; dual-supply ±0.85V to ±2.75V. Absolute max supply voltage 6V.
3 -IN input Inverting input of the operational amplifier. Input bias current typically 10fA (±0.01pA typ, 0.8pA max at 25°C).
4 OUT output Amplifier output. Rail-to-rail output with 60mA high output current drive; short-circuit current typically 60mA (45mA min) at VS = 5.5V. Open-loop output impedance ~1.6kΩ at 1MHz.
5 V+ power_in Positive (highest) power supply. Supply range 1.7V to 5.5V (single-supply). Quiescent current typically 24µA per amplifier.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
opa391dckr.step 87 KB You want the bare part, or you mark your own boards.
opa391dckr-etched.step 1.9 MB You want the part with OPA391DCKR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 478 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 (44 pp, sha256 47047209423c48c4, 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).
