LF353MX

Texas Instruments · FET InputAmplifiers · SOIC-8

LF353MX 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 OUTA output Output of op-amp A. Drives ±13.5 V typical swing with VS=±15 V, RL=10 kΩ. Short-circuit protected (continuous).
2 IN-A input Inverting input of op-amp A. JFET input, input resistance ~10^12 Ω, bias current ~50 pA typical.
3 IN+A input Non-inverting input of op-amp A. JFET input, input common-mode range typically +15/−12 V at VS=±15 V.
4 V- power_in Negative supply rail (VEE). Operating range up to ±18 V absolute max; typical dual-supply operation at ±15 V.
5 IN+B input Non-inverting input of op-amp B. JFET input matching op-amp A.
6 IN-B input Inverting input of op-amp B. JFET input matching op-amp A.
7 OUTB output Output of op-amp B. Same drive characteristics as OUTA; ±13.5 V typical swing, short-circuit protected.
8 V+ power_in Positive supply rail (VCC). Operating range up to ±18 V absolute max; supply current 3.6 mA typical (6.5 mA max).

CAD (KiCad official)

  • Symbol: LF353MX
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: lf353mx-etched.step / lf353mx-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lf353mx.step / lf353mx.glb are the bare package body.

Provenance

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

  • Datasheet: Texas Instruments datasheet (17 pp, sha256 603a365e35bc9fae, 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).
