LM833MX

Texas Instruments · Audio Power OpAmps · SOIC-8

LM833MX 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 OUT A output Output of op-amp channel A. Low-impedance audio output capable of driving typical audio loads.
2 IN A- input Inverting input of op-amp channel A. High-impedance differential input.
3 IN A+ input Non-inverting input of op-amp channel A. High-impedance differential input.
4 V- power_in Negative supply rail. Typically -5 V to -18 V for dual-supply operation, or GND for single-supply operation.
5 IN B+ input Non-inverting input of op-amp channel B. High-impedance differential input.
6 IN B- input Inverting input of op-amp channel B. High-impedance differential input.
7 OUT B output Output of op-amp channel B. Low-impedance audio output capable of driving typical audio loads.
8 V+ power_in Positive supply rail. Typically +5 V to +18 V for dual-supply operation, or up to +36 V for single-supply operation.

CAD (KiCad official)

  • Symbol: LM833MX
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: lm833mx-etched.step / lm833mx-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm833mx.step / lm833mx.glb are the bare package body.

Provenance

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

  • Datasheet: Texas Instruments datasheet (27 pp, sha256 761f589c3a22a683, 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).
