LF353DR

Texas Instruments · FET InputAmplifiers · SOIC-8

LF353DR 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 op-amp 1. Maximum peak output voltage swing ±13.5 V typ into RL = 10 kΩ (VCC±=±15 V).
2 1IN- input Inverting input of op-amp 1. JFET input, input bias current 50 pA typ, input impedance ~10^12 Ω.
3 1IN+ input Noninverting input of op-amp 1. JFET input, input bias current 50 pA typ, common-mode input range VCC- +4 V to VCC+ -4 V.
4 VCC- power_in Negative supply voltage. Recommended -3.5 V to -18 V; absolute max -18 V. Shared between both op-amps.
5 2IN+ input Noninverting input of op-amp 2. JFET input, input bias current 50 pA typ, common-mode input range VCC- +4 V to VCC+ -4 V.
6 2IN- input Inverting input of op-amp 2. JFET input, input bias current 50 pA typ, input impedance ~10^12 Ω.
7 2OUT output Output of op-amp 2. Maximum peak output voltage swing ±13.5 V typ into RL = 10 kΩ (VCC±=±15 V).
8 VCC+ power_in Positive supply voltage. Recommended 3.5 V to 18 V; absolute max 18 V. Supply current 3.6 mA typ. Shared between both op-amps.

CAD (KiCad official)

  • Symbol: LF353DR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: lf353dr-etched.step / lf353dr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lf353dr.step / lf353dr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lf353dr.step 122 KB You want the bare part, or you mark your own boards.
lf353dr-etched.step 1.7 MB You want the part with LF353DR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 420 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 (21 pp, sha256 60f31c89a860fa37, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
