ADR443ARZ-REEL7

Analog Devices · Voltage References · SOIC-8

ADR443ARZ-REEL7 from Analog Devices, 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; the datasheet says not to connect anything to this pin.
2 VIN power_in Input voltage connection; the ADR443 operating supply range is 3.5 V to 18 V.
3 NIC unconnected Not Internally Connected; this pin is not connected internally.
4 GND power_in Ground reference pin for the reference.
5 TRIM passive Output voltage trim terminal, which allows the output to be adjusted over a ±0.5% range without compromising performance.
6 VOUT power_out Output voltage of 3.000 V nominal for the ADR443, sourcing up to 10 mA and sinking up to −5 mA.
7 NIC unconnected Not Internally Connected; this pin is not connected internally.
8 DNC unconnected Do Not Connect; the datasheet says not to connect anything to this pin.

CAD (KiCad official)

  • Symbol: ADR443ARZ-REEL7
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: adr443arz-reel7-etched.step / adr443arz-reel7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); adr443arz-reel7.step / adr443arz-reel7.glb are the bare package body.
