ADR4525BRZ

Overview

The ADR4525BRZ-R7 is a high-precision, low-power voltage reference with a fixed output of 2.5 V. It features a maximum initial error of ±0.02% and a temperature coefficient of 2 ppm/°C over the −40°C to +125°C range. The device operates on an input voltage of 3 V to 15 V, drawing a maximum quiescent current of 950 μA. It provides an output current capacity of +10 mA source and −10 mA sink, with a maximum dropout voltage of 300 mV at 2 mA. Output noise is 1.25 μV p-p from 0.1 Hz to 10 Hz.

Feature Summary

• Utilizes innovative core topology for industry-leading temperature stability and noise performance.
• Features low thermal-induced output voltage hysteresis and low long-term drift for improved accuracy.
• Supports both sourcing (+10 mA) and sinking (−10 mA) load currents.

Applications

• Precision data acquisition systems
• High resolution data converters
• Medical devices

Procurement Notes

Verify the specific grade suffix against the ordering guide to confirm the operating temperature range and performance specifications. Ensure the package type matches the design requirements, as the family includes SOIC and LCC options. Confirm that the selected variant meets the required line regulation and load regulation parameters for the target application environment.

Selection Notes

Select this component when a fixed 2.5 V reference is required with high accuracy and low noise. The B grade offers extended industrial temperature operation suitable for harsh environments. Consider the low quiescent current and dropout voltage for battery-powered or portable equipment designs where power efficiency is critical.

Part Context

The ADR4525BRZ-R7 belongs to the ADR45xx series of ultralow noise, high accuracy voltage references. This family shares common architectural features but varies in output voltage and available grades. The BRZ suffix indicates an 8-lead SOIC package with B grade performance specifications.
