REF5040MDREP

Texas Instruments · Voltage Reference · SOIC-8

REF5040MDREP 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 DNC unconnected Do not connect.
2 VIN power_in Power supply input ranging from VOUT + 0.2 V to 18 V maximum with recommended bypass capacitor 1 µF to 10 µF.
3 TEMP output Temperature monitoring output provides chip temperature-dependent voltage with approximately 60 kΩ source impedance.
4 GND power_in System ground.
5 TRIM/NR input Trim and noise reduction input for output voltage adjustment; connecting 1 µF capacitor creates low-pass filter at bandgap reducing output noise.
6 VOUT output Factory-trimmed reference voltage output nominally 4.096 V with recommended load capacitor 1 µF to 50 µF, ESR 1 to 1.5 Ω.
7 NC unconnected No internal connection.
8 DNC unconnected Do not connect.

CAD (KiCad official)

  • Symbol: REF5040MDREP
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: ref5040mdrep-etched.step / ref5040mdrep-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ref5040mdrep.step / ref5040mdrep.glb are the bare package body.

Provenance

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

  • Datasheet: Texas Instruments datasheet (30 pp, sha256 57d711031fe8f29e, retrieved 2026-10-07, tier: lcsc)
