ADR423ARZ-REEL7

Overview

The ADR423ARZ-REEL7 is a series precision voltage reference manufactured by Analog Devices Inc., featuring a fixed output voltage of 3.00 V. It utilizes second-generation XFET technology to achieve low noise and high accuracy. The device operates within an input voltage range of 5 V to 18 V and draws a maximum quiescent current of 0.5 mA. It provides a maximum load current of 10 mA with a line regulation of 35 ppm/V and load regulation of 70 ppm/mA. The unit is housed in an 8-lead SOIC package and functions reliably across an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Utilizes patented XFET architecture for superior thermal hysteresis and low noise performance compared to band gap references.
• Features a dedicated trim terminal allowing output voltage adjustment over a ±0.5% range without compromising other electrical characteristics.
• Incorporates temperature drift curvature correction techniques to minimize nonlinearity of the voltage change with temperature.

Applications

• Precision data acquisition systems
• High resolution converters
• Portable medical instruments
