ADR434ARMZ

Analog Devices · Voltage References · MSOP-8

ADR434ARMZ from Analog Devices, in a MSOP-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; for the ADR434 the supply operating range is 6.1 V to 18 V.
3 NIC unconnected Not internally connected; this pin is not connected internally.
4 GND power_in Ground reference connection.
5 TRIM input Output voltage trim terminal, which adjusts the output over a ±0.5% range without compromising performance.
6 VOUT power_out Output voltage; the reference can source up to 30 mA and sink up to −20 mA.
7 COMP passive Compensation input; connect a series resistor and capacitor network from COMP to VOUT to reduce overall noise, and leave unconnected if unused.
8 DNC unconnected Do not connect; do not connect to this pin.

CAD (KiCad official)

  • Symbol: ADR434ARMZ
  • Footprint: Package_SO:MSOP-8_3x3mm_P0.65mm
  • 3D model: MSOP-8 (KiCad packages3D, STEP)
  • 3D model files: adr434armz-etched.step / adr434armz-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); adr434armz.step / adr434armz.glb are the bare package body.
