ADR443BRZ

Analog Devices · Voltage References · SOIC-8

ADR443BRZ 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; do not connect to this pin.
2 VIN power_in Input voltage connection; supply range 3.5 V to 18 V for ADR443 (VOUT + 500 mV headroom), 20 V absolute maximum.
3 NIC unconnected Not Internally Connected; this pin is not connected internally.
4 GND power_in Ground.
5 TRIM input Output voltage trim pin, allowing adjustment of the output voltage over a ±0.5% range via a potentiometer between VOUT and GND.
6 VOUT power_out Output voltage (3.000 V for ADR443), sources up to 10 mA and sinks up to -5 mA.
7 NIC unconnected Not Internally Connected; this pin is not connected internally.
8 DNC unconnected Do Not Connect; do not connect to this pin.

CAD (KiCad official)

  • Symbol: ADR443BRZ
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: adr443brz-etched.step / adr443brz-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); adr443brz.step / adr443brz.glb are the bare package body.
