ADR4520BRZ

Overview

The ADR4520BRZ is a precision series voltage reference from Analog Devices, providing a fixed output of 2.048 V. It features a maximum initial accuracy of ±0.02% and a temperature coefficient of 2 ppm/°C over the extended industrial range of −40°C to +125°C. The device operates with an input voltage between 3 V and 15 V, drawing a maximum quiescent current of 950 μA. It supports up to 10 mA sourcing and sinking current, ensuring stability under varying load conditions.

Feature Summary

Utilizes innovative core topology for industry-leading temperature stability and low noise performance
Provides high accuracy with minimal long-term drift and low thermally induced hysteresis
Capable of sourcing and sinking current to support diverse load requirements

Applications

Precision data acquisition systems
High resolution data converters
Industrial instrumentation
Medical devices

Procurement Notes

Verify the specific grade suffix (B) against project requirements to ensure compliance with the specified temperature coefficient and initial accuracy limits. Confirm that the SOIC-8 package aligns with the PCB footprint design. Ensure the input voltage supply remains within the 3 V to 15 V operational range to maintain specified regulation characteristics.

Selection Notes

Select this component when a stable 2.048 V reference is required for high-precision analog signal chains. Consider the B grade specifications for extended temperature operation. Evaluate the low dropout voltage capability relative to the available supply headroom in portable or battery-powered designs.

Part Context

This part belongs to the ADR45xx family of ultralow noise voltage references manufactured by Analog Devices. The family includes variants with different fixed output voltages such as 2.5 V, 3.0 V, and 3.3 V. All members share similar architectural benefits regarding noise performance and power efficiency.
