OPA1612AIDR

Texas Instruments · Audio Power OpAmps · SOIC-8

OPA1612AIDR from Texas Instruments, in a SOIC-8. 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 channel A op-amp. Rail-to-rail output capable of driving ±30 mA into loads down to 600 Ω with the specified low distortion.
2 -IN A input Inverting input, channel A. Bipolar input with typical ±60 nA bias current; common-mode range (V-)+2 V to (V+)-2 V.
3 +IN A input Noninverting input, channel A. Bipolar input with typical ±60 nA bias current; common-mode range (V-)+2 V to (V+)-2 V.
4 V- power_in Negative (lowest) power supply. Total supply (V+)-(V-) rated 4.5 V to 36 V (±2.25 V to ±18 V dual-supply). Quiescent current 3.6 mA per channel.
5 +IN B input Noninverting input, channel B. Bipolar input with typical ±60 nA bias current; common-mode range (V-)+2 V to (V+)-2 V.
6 -IN B input Inverting input, channel B. Bipolar input with typical ±60 nA bias current; common-mode range (V-)+2 V to (V+)-2 V.
7 OUT B output Output of channel B op-amp. Rail-to-rail output capable of driving ±30 mA into loads down to 600 Ω with the specified low distortion.
8 V+ power_in Positive (highest) power supply. Total supply (V+)-(V-) rated 4.5 V to 36 V (±2.25 V to ±18 V dual-supply). Quiescent current 3.6 mA per channel.

CAD (KiCad official)

  • Symbol: OPA1612AIDR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: opa1612aidr-etched.step / opa1612aidr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); opa1612aidr.step / opa1612aidr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
opa1612aidr.step 122 KB You want the bare part, or you mark your own boards.
opa1612aidr-etched.step 2.0 MB You want the part with OPA1612AIDR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 513 faces against 147 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 (31 pp, sha256 2ca72d8fc7b9ac8d, 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).
