ADR292ERZ

Voltage Reference Overview

The ADR292ERZ is a low noise, micropower precision voltage reference providing a fixed output of 4.096 V. It utilizes the XFET architecture to achieve high stability and low thermal drift. The device operates within a supply range of 4.4 V to 15 V with a maximum supply current of 15 μA. Initial accuracy is specified at ±0.07%, and the temperature coefficient is 8 ppm/°C. It supports an output current of up to 5 mA and functions reliably across an extended industrial temperature range from −40°C to +125°C.

Voltage Reference Procurement Notes

Verify the specific electrical grade and package configuration against project requirements before procurement. Confirm that the supply voltage meets the minimum operating threshold of 4.4 V for proper regulation. Ensure compatibility with the 8-lead SOIC footprint during PCB layout. Check for any updated datasheet revisions or ordering suffixes that may affect availability or specifications.

Voltage Reference Selection Notes

Select this component when a 4.096 V output is required with high initial accuracy and low temperature drift. The XFET technology offers superior noise performance compared to traditional band gap references. Consider the 8-lead SOIC package for surface mount assembly. Evaluate power dissipation constraints if operating near maximum input voltages or load currents.
