Description
ADR420ARMZ is a fixed-output precision voltage reference from Analog Devices. It provides a stable, low-noise reference for ADCs, DACs, and instrumentation, enabling accurate measurements and calibration. The device emphasizes low drift, low noise, and good line/load regulation, making it suitable for precision instrumentation and data-acquisition systems. The ARMZ suffix denotes the packaging variant; refer to the datasheet for the exact package. Typical applications include precision ADC/DAC references, sensor interfaces, and calibration references in systems requiring a stable reference. Operation requires proper decoupling and a stable supply; consult the datasheet for recommended capacitors, pinout, maximum output current, and temperature range. For exact electrical specs, pinout, and package details, see Analog Devices’ ADR420ARMZ datasheet.
Equivalent
I need specs to give exact equivalents. Please confirm:
- Vref value (voltage)
- tolerance and tempco
- package/type (e.g., MSOP8)
With those, I’ll provide precise cross-references (e.g., TI/Onsemi/Analog devices parts).
