LF411CDR

Texas Instruments · Operational Amplifier · SOIC-8

LF411CDR 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 BAL1 input Offset null / balance pin 1. Connect a potentiometer (typ. 10 kΩ) between BAL1 and BAL2 with the wiper tied to VCC- to trim input offset voltage to zero.
2 IN- input Inverting input of the op-amp. High-impedance JFET input (~10^12 Ω), input bias current 50 pA typ.
3 IN+ input Non-inverting input of the op-amp. High-impedance JFET input (~10^12 Ω), input bias current 50 pA typ.
4 VCC- power_in Negative supply rail. Recommended operating range -3.5 V to -18 V; absolute maximum -18 V. In single-supply operation connect to GND.
5 BAL2 input Offset null / balance pin 2. Used with BAL1 and a trim potentiometer (wiper to VCC-) to null input offset voltage.
6 OUT output Op-amp output. Peak output-voltage swing ±13.5 V typ at RL=10 kΩ with ±15 V supplies; short-circuit protected (unlimited duration).
7 VCC+ power_in Positive supply rail. Recommended operating range 3.5 V to 18 V; absolute maximum 18 V.
8 NC unconnected No internal connection. Leave floating or tie to any convenient potential.

CAD (KiCad official)

  • Symbol: LF411CDR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: lf411cdr-etched.step / lf411cdr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lf411cdr.step / lf411cdr.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (11 pp, sha256 1e51951a18976c2b, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
