TL3472IDR

Texas Instruments · Operational Amplifier · SOIC-8

TL3472IDR 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 1OUT output Output of amplifier channel 1. Short-circuit protected; max output current ±80mA.
2 1IN- input Inverting input of amplifier channel 1. Input voltage must remain within VCC- to VCC+; input current limited to ±1mA.
3 1IN+ input Non-inverting input of amplifier channel 1. Common-mode input voltage range includes ground (VCC-) up to VCC+ - ~1.5V.
4 VCC-/GND power_in Negative supply / ground pin. Tied to GND in single-supply operation, or to the negative rail in split-supply operation (down to -18V absolute max). Total current out of VCC- limited to 80mA.
5 2IN+ input Non-inverting input of amplifier channel 2. Common-mode input range includes ground (VCC-).
6 2IN- input Inverting input of amplifier channel 2. Input current limited to ±1mA; differential input voltage max ±36V.
7 2OUT output Output of amplifier channel 2. Short-circuit protected; max output current ±80mA.
8 VCC+ power_in Positive supply pin. Single-supply range 4V to 36V (absolute max 18V referenced to midpoint, i.e. ±18V split). Total current into VCC+ limited to 80mA.

CAD (KiCad official)

  • Symbol: TL3472IDR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: tl3472idr-etched.step / tl3472idr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tl3472idr.step / tl3472idr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
tl3472idr.step 122 KB You want the bare part, or you mark your own boards.
tl3472idr-etched.step 1.7 MB You want the part with TL3472IDR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 429 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 (18 pp, sha256 d336c82277cfbb67, 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).
