ADR444ARZ-REEL7

Analog Devices · Voltage References · SOIC-8

ADR444ARZ-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; for the ADR444 the supply operating range is 4.6 V to 18 V, with a minimum headroom of 500 mV above VOUT.
3 NIC unconnected Not internally connected; this pin is not connected inside the device.
4 GND power_in Ground connection for the device.
5 TRIM passive Output voltage trim; allows the output voltage to be adjusted over a 0.5% range without compromising performance, typically via a potentiometer between VOUT and GND with the wiper on TRIM.
6 VOUT power_out Output voltage; the device can source up to 10 mA and sink 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: ADR444ARZ-REEL7
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: adr444arz-reel7-etched.step / adr444arz-reel7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); adr444arz-reel7.step / adr444arz-reel7.glb are the bare package body.
