LM285MX-1.2

Texas Instruments · Voltage Reference · SOIC-8

LM285MX-1.2 from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No internal connection; not connected to the die per the SOIC connection diagram.
2 NC unconnected No internal connection; not connected to the die per the SOIC connection diagram.
3 NC unconnected No internal connection; not connected to the die per the SOIC connection diagram.
4 - passive Negative (anode) terminal of the 2-terminal band-gap voltage reference diode, the low side of the reverse-breakdown voltage measured to pin 8.
5 NC unconnected No internal connection; not connected to the die per the SOIC connection diagram.
6 NC unconnected No internal connection; not connected to the die per the SOIC connection diagram.
7 NC unconnected No internal connection; not connected to the die per the SOIC connection diagram.
8 + passive Positive (cathode) terminal of the 2-terminal band-gap voltage reference diode; operated in reverse breakdown over 10μA to 20mA with a nominal 1.235V (1.223V-1.247V) drop to pin 4.

CAD (KiCad official)

  • Symbol: LM285MX-1.2
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: lm285mx-1-2-etched.step / lm285mx-1-2-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm285mx-1-2.step / lm285mx-1-2.glb are the bare package body.

Provenance

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

  • Datasheet: Texas Instruments datasheet (30 pp, sha256 f069722c4b8202b3, retrieved 2026-09-29, tier: lcsc)
  • 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).
