ADR423BRZ

Overview

The ADR423BRZ is a second-generation XFET voltage reference providing a fixed 3.00 V output in an 8-lead SOIC package. It features B-grade initial accuracy of ±0.04% and a temperature coefficient of 3 ppm/°C over the -40°C to +125°C range. The device operates with a supply voltage from 5 V to 18 V, drawing a maximum quiescent current of 500 µA while delivering up to 10 mA of load current. Low noise performance is specified at 2.0 µV p-p (0.1 Hz to 10 Hz), with long-term stability rated at 50 ppm per 1000 hours.

Feature Summary

Utilizes patented XFET technology for superior thermal hysteresis and low noise compared to band gap references.
Includes a dedicated trim terminal allowing output voltage adjustment within a ±0.5% range without degrading temperature coefficients.
Offers high output drive capability of 10 mA with minimal supply headroom requirements.

Applications

Precision data acquisition systems
High resolution analog-to-digital converters
Optical network control circuits

Procurement Notes

Verify the specific suffix 'BRZ' corresponds to the B-grade electrical specifications and tube packaging configuration. Confirm that the 8-lead SOIC footprint matches the target PCB layout dimensions. Ensure the input voltage remains above the minimum operating threshold of 5 V to maintain regulation.

Selection Notes

Select this component when a 3.00 V reference is required with high precision and low drift. Compare against the ADR421 or ADR425 if different nominal voltages are needed. Consider the MSOP variant if board space is constrained, as it shares identical electrical characteristics but offers a smaller footprint.

Part Context

This part belongs to the ADR42x series of ultraprecision voltage references manufactured by Analog Devices. The series includes variants with outputs of 2.048 V, 2.500 V, and 5.000 V. All members share the same core XFET architecture and pinout compatibility.
