AD5292SRUZ-20-EP

Digital Potentiometers Overview

The AD5292SRUZ-20-EP is a single-channel, 1024-position digital potentiometer featuring nonvolatile memory and enhanced product specifications for defense and aerospace applications. It offers a nominal resistance of 20 kΩ with a maximum ±1% tolerance error in resistor performance mode. The device supports SPI-compatible serial interfaces and includes 20-times programmable (20-TP) wiper memory. Operating temperatures range from −55°C to +125°C, with supply voltages spanning +9 V to +33 V single-supply or ±9 V to ±16.5 V dual-supply configurations.

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix 'Z' indicates RoHS compliance when sourcing this component. Confirm that the Enhanced Product (EP) designation aligns with project requirements for controlled manufacturing baselines and qualification data availability. Ensure supply chain channels can support the specialized nature of defense-grade components.

Digital Potentiometers Selection Notes

Select this model for applications requiring high precision with a maximum ±1% resistor tolerance error. The 20-TP memory allows for permanent programming of the wiper position, suitable for fixed calibration needs. Verify that the operating voltage range (+9 V to +33 V single or ±9 V to ±16.5 V dual) matches the system power architecture.

Digital Potentiometers Part Context

This component belongs to the AD5292-EP Enhanced Product family, designed specifically for defense and aerospace (AQEC) applications. It shares core functionality with standard AD5292 devices but features a controlled manufacturing baseline, single assembly/test site, and single fabrication site to ensure consistency and reliability.

Digital Potentiometers Replacement Considerations

The AD5292SRU-20-EP is functionally equivalent but lacks RoHS compliance. Standard commercial versions like the AD5292BRUZ-20 do not meet the extended temperature range or enhanced product qualifications required for AQEC applications.
