ADR434TRZ-EP-R7

Overview

The ADR434TRZ-EP-R7 is a low noise XFET voltage reference featuring high accuracy and low temperature drift. It provides a fixed output voltage of 4.096 V with an initial accuracy of ±1.5 mV (±0.04%). The device operates within a supply voltage range of 6.1 V to 18 V, drawing a typical quiescent current of 800 µA. It supports military temperature specifications from −55°C to +125°C and offers a maximum temperature coefficient of 3 ppm/°C.

Feature Summary

• Utilizes patented XFET technology for minimized voltage change versus temperature nonlinearity.
• Capable of sourcing up to +10 mA and sinking up to -10 mA of output current.
• Includes a dedicated trim terminal for adjusting output voltage without compromising performance.

Applications

• Precision data acquisition systems
• High resolution data converters
• Optical control circuits

Procurement Notes

Verify the component matches the specific Enhanced Product (EP) designation required for defense or aerospace applications. Confirm that the ordering suffix corresponds to the reel packaging format. Ensure the procurement channel sources parts compliant with the controlled manufacturing baseline and enhanced product change notification protocols specified by Analog Devices.

Selection Notes

Select this component when a stable 4.096 V reference is needed in environments requiring military-grade temperature resilience. The part is suitable for 5 V system architectures due to its low supply voltage headroom requirement. Consider the available trim terminal if precise voltage adjustment is necessary during circuit calibration.

Part Context

This component belongs to the ADR43x-EP series of XFET voltage references manufactured by Analog Devices. It shares architectural similarities with the ADR431-EP and ADR435-EP models but is distinguished by its specific 4.096 V output voltage rating. The EP designation indicates it meets the AQEC standard for enhanced reliability.
