REF2041AIDDCT

Texas Instruments · Voltage Reference · SOT-23-5

REF2041AIDDCT from Texas Instruments, in a SOT-23-5. 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 VBIAS output Bias voltage output equal to VREF / 2.
2 GND power_in Ground reference pin.
3 EN input Enable input; the device is enabled when EN is at or above VIN - 0.7 V.
4 VIN power_in Input supply voltage; recommended range is VREF + 0.02 V (minimum) to 5.5 V at IL = 0 mA and TA = 25°C.
5 VREF power_in Reference voltage output; 4.096 V for the REF2041.

CAD (KiCad official)

  • Symbol: REF2041AIDDCT
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: ref2041aiddct-etched.step / ref2041aiddct-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ref2041aiddct.step / ref2041aiddct.glb are the bare package body.

Provenance

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

  • Datasheet: Texas Instruments datasheet (37 pp, sha256 2b21e0c5aea93ed7, retrieved 2026-11-05, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
