ADR435TRZ-EP-R7

Overview

The ADR435TRZ-EP-R7 is a low noise XFET voltage reference with an output of 5.0 V and initial accuracy of ±0.04%. It operates within a supply range of 7.0 V to 18 V, drawing 800 µA quiescent current. The device features a maximum temperature coefficient of 3 ppm/°C over the military range of −55°C to +125°C. It provides high output source and sink currents of ±10 mA and includes a trim terminal for voltage adjustment.

Feature Summary

• Utilizes patented XFET technology for minimized voltage change versus temperature nonlinearity.
• Supports defense and aerospace applications through AQEC standard compliance.
• Features controlled manufacturing baseline with single assembly, test, and fabrication sites.

Applications

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

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm RoHS compliance status and ensure the ordering suffix matches the required reel quantity. Validate that the part meets the specific military temperature range requirements for your application environment.

Selection Notes

Select this model for applications requiring strict military temperature stability and enhanced product reliability. The fixed 5.0 V output suits 5 V system architectures. Consider the trim pin if minor voltage adjustments are needed without compromising performance. Ensure input voltage headroom exceeds 2 V above the output level.

Part Context

This component belongs to the ADR43x-EP series of enhanced product voltage references. It shares the same package and core architecture as other variants in the family but is optimized for 5.0 V output. The EP designation indicates qualification for aerospace and defense environments with controlled manufacturing processes.
