TL972IDR

Texas Instruments · Operational Amplifier · SOIC-8

TL972IDR 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 OUT1 output Op-amp channel 1 output. Rail-to-rail output stage swings to within ~100 mV of the supply rails under light load.
2 IN1- input Inverting input of op-amp channel 1. Differential input voltage limited to ±1 V absolute maximum with respect to the non-inverting input.
3 IN1+ input Non-inverting input of op-amp channel 1. Common-mode input range is Vcc-+1.15 V to Vcc+-1.15 V.
4 VCC- power_in Negative supply rail. Connect to GND for single-supply operation, or to the negative rail for split-supply operation. Total supply range Vcc+ - Vcc- = 2.7 V to 12 V (15 V abs max).
5 IN2+ input Non-inverting input of op-amp channel 2. Common-mode input range is Vcc-+1.15 V to Vcc+-1.15 V.
6 IN2- input Inverting input of op-amp channel 2. Differential input voltage limited to ±1 V absolute maximum with respect to the non-inverting input.
7 OUT2 output Op-amp channel 2 output. Rail-to-rail output stage swings to within ~100 mV of the supply rails under light load.
8 VCC+ power_in Positive supply rail. Connect to the positive supply (single- or split-supply). Total supply range Vcc+ - Vcc- = 2.7 V to 12 V (15 V abs max). Bypass with a 0.1 µF ceramic close to the pin.

CAD (KiCad official)

  • Symbol: TL972IDR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: tl972idr-etched.step / tl972idr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tl972idr.step / tl972idr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
tl972idr.step 122 KB You want the bare part, or you mark your own boards.
tl972idr-etched.step 1.5 MB You want the part with TL972IDR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 390 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 (38 pp, sha256 b71e65741c035ae3, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
