AD5292SRU-20-EP

Digital Potentiometers Overview

The AD5292SRU-20-EP is a single-channel, 1024-position digital potentiometer from Analog Devices, designed for enhanced product applications including defense and aerospace. It features 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) nonvolatile memory that refreshes wiper settings at power-on. Operating ranges include +9 V to +33 V single-supply or ±9 V to ±16.5 V dual-supply configurations, with an extended temperature range of −55°C to +125°C.

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix 'SRU' against the manufacturer's current ordering guide to confirm package type and RoHS compliance status. Confirm availability through authorized distributors as this is an Enhanced Product variant. Ensure supply chain controls meet AQEC requirements if used in defense or aerospace contexts.

Digital Potentiometers Selection Notes

Select this component when high precision is required, specifically utilizing the Resistor Performance Mode for ±1% tolerance. Ensure the system voltage falls within the +9 V to +33 V single-supply or ±9 V to ±16.5 V dual-supply limits. Verify that the SPI interface timing parameters align with the host controller's capabilities, particularly regarding the SYNC and SCLK constraints.

Digital Potentiometers Part Context

This part belongs to the AD5292-EP Enhanced Product family, distinguished by controlled manufacturing baselines and qualification data suitable for rigorous environments. It shares functional similarities with standard AD5292 devices but offers extended temperature operation and stricter quality controls. The SRU designation indicates the 14-lead TSSOP package option.

Digital Potentiometers Replacement Considerations

Standard AD5292BRUZ-20 variants offer similar electrical performance but lack the Enhanced Product qualifications and extended temperature range. Substitution requires verifying that the lower temperature rating (-40°C to +125°C) meets application requirements and that AQEC compliance is not mandatory.
