TL081IDR

Texas Instruments · FET InputAmplifiers · SOIC-8

TL081IDR 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 NC unconnected No internal connection. Do not connect. On the TL081C PS package this pin is OFFSET N1, but on the D (SOIC) package used by TL081IDR it is NC.
2 IN- input Inverting input of the op amp. High-impedance JFET input; typical input bias current is in the tens of pA at 25°C.
3 IN+ input Non-inverting input of the op amp. High-impedance JFET input; common-mode input range includes VCC+.
4 VCC- power_in Negative supply pin. Connect to the negative rail in dual-supply operation (down to -20V) or to GND in single-supply operation. Total supply range 4.5V to 40V.
5 NC unconnected No internal connection on the D (SOIC-8) package. Do not connect. (This pin is OFFSET N2 on the PS/TL081C variant only.)
6 OUT output Op-amp output. Push-pull output with short-circuit protection; class-AB output stage.
7 VCC+ power_in Positive supply pin. Connect to the positive rail (up to +20V for dual supply, up to 40V single supply). Bypass locally with a 0.1µF capacitor to VCC-.
8 NC unconnected No internal connection. Do not connect.

Two STEP files. Same geometry, different body top:

File Size Use it when
tl081idr.step 122 KB You want the bare part, or you mark your own boards.
tl081idr-etched.step 1.7 MB You want the part with TL081IDR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 423 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 (78 pp, sha256 6a831542dbeee1d7, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
