Overview

The Analog Devices ADR291ERZ is a high-precision, fixed 2.5V series voltage reference designed for applications demanding exceptional stability and low drift. Its ±0.08% initial tolerance and 8ppm/°C temperature coefficient are critical for maintaining accurate voltage rails in sensitive instrumentation. A key design consideration when utilizing this device is the trade-off between its low quiescent current (15µA) and its limited output current capability (5 mA); exceeding this limit can compromise its tight regulation and introduce instability, necessitating careful output load analysis.

Key Features

Output Voltage: 2.5V (Fixed)
Initial Tolerance: ±0.08%
Temperature Coefficient: 8ppm/°C
Output Current: 5 mA
Quiescent Current: 15µA
Package: 8-SOIC (3.90mm Width)

Applications

The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.

Precision data acquisition system analog front-ends
Low-power battery-operated sensor calibration circuits
High-resolution analog-to-digital converter (ADC) reference
Stable bias voltage generation for optical modules
