LF412CDR

Texas Instruments · FET InputAmplifiers · SOIC-8-150mil

LF412CDR from Texas Instruments, in a SOIC-8-150mil. 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 Amplifier 1 output. Max peak output voltage swing +/-13.5 V typ into 10 kOhm load at +/-15 V supplies.
2 1IN- input Amplifier 1 inverting input. JFET input with ~10^12 Ohm input impedance and 50 pA typ input bias current.
3 1IN+ input Amplifier 1 non-inverting input. JFET input with ~10^12 Ohm input impedance and 50 pA typ input bias current.
4 VCC- power_in Negative supply rail. Recommended -3.5 V to -18 V; absolute maximum -18 V.
5 2IN+ input Amplifier 2 non-inverting input. JFET input with ~10^12 Ohm input impedance and 50 pA typ input bias current.
6 2IN- input Amplifier 2 inverting input. JFET input with ~10^12 Ohm input impedance and 50 pA typ input bias current.
7 2OUT output Amplifier 2 output. Max peak output voltage swing +/-13.5 V typ into 10 kOhm load at +/-15 V supplies.
8 VCC+ power_in Positive supply rail. Recommended 3.5 V to 18 V; absolute maximum 18 V. Supply current 4.5 mA typ, 6.8 mA max.

CAD (KiCad official)

  • Symbol: LF412CDR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8-150mil (KiCad packages3D, STEP)
  • 3D model files: lf412cdr-etched.step / lf412cdr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lf412cdr.step / lf412cdr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lf412cdr.step 122 KB You want the bare part, or you mark your own boards.
lf412cdr-etched.step 1.5 MB You want the part with LF412CDR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 392 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 (10 pp, sha256 1c0813ea36559238, 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).
