LM61CIM3X

Texas Instruments · Temperature and Humidity Sensor · SOT-23

LM61CIM3X from Texas Instruments, in a SOT-23. 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 +VS power_in Positive power supply pin. Operating range 2.7 V to 10 V (absolute max 12 V). Typical quiescent current 82 µA (125 µA max).
2 VO output Temperature sensor analog output. VO = (10 mV/°C × T°C) + 600 mV. Output impedance ≈800 Ω; drive to ground through no less than internal spec, output current max 10 mA.
3 GND power_in Device ground pin, connected to power supply negative terminal.

Two STEP files. Same geometry, different body top:

File Size Use it when
lm61cim3x.step 59 KB You want the bare part, or you mark your own boards.
lm61cim3x-etched.step 1.4 MB You want the part with LM61CIM3X already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 362 faces against 69 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 (27 pp, sha256 c943a6e73227c5f3, retrieved 2026-08-17, 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).
