ADR441ARZ

Analog Devices · Voltage References · SOIC-8

ADR441ARZ 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 ADR441 operating range is 3 V to 18 V, with supply headroom of 500 mV (VIN − VOUT).
3 NIC unconnected Not internally connected; this pin is not connected inside the device.
4 GND power_in Ground reference for the reference circuit.
5 TRIM passive Output voltage trim terminal, used with an external potentiometer between VOUT and GND to adjust the output by ±0.5% without degrading performance.
6 VOUT power_out Output voltage; the ADR441 sources up to 10 mA and sinks up to −5 mA.
7 NIC unconnected Not internally connected; this pin is not connected inside the device.
8 DNC unconnected Do Not Connect; the datasheet says not to connect anything to this pin.

CAD (KiCad official)

  • Symbol: ADR441ARZ
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: adr441arz-etched.step / adr441arz-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); adr441arz.step / adr441arz.glb are the bare package body.
