Digital Potentiometers Overview

The AD5291BRUZ-100-RL7 is a single-channel digital potentiometer featuring 256-position resolution and a nominal resistance of 100 kΩ. It operates with a single supply voltage ranging from +9 V to +33 V or dual supplies of ±9 V to ±16.5 V, utilizing a logic supply between 2.7 V and 5.5 V. The device incorporates SPI-compatible serial interface for wiper control and includes nonvolatile memory capable of storing up to 20 programmable wiper positions. It guarantees a maximum resistor tolerance error of ±1% in performance mode and functions within an extended industrial temperature range of −40°C to +105°C.

Digital Potentiometers Feature Summary

Programmable voltage-to-current conversion
Sensor calibration

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix RL7 corresponds to the required tape and reel packaging configuration. Confirm that the BRUZ variant matches the necessary temperature grade and package type requirements for the target application environment before finalizing procurement.

Digital Potentiometers Selection Notes

Select this component when high-voltage single-ended or bipolar signal adjustment is required without external amplification. The 100 kΩ resistance value suits applications needing moderate current handling. Ensure the system logic level supports the 2.7 V to 5.5 V VLOGIC range for reliable SPI communication.

Digital Potentiometers Part Context

This part belongs to the AD5291/AD5292 family of digital potentiometers. The AD5291 variant specifically provides 8-bit (256-position) resolution, whereas the AD5292 offers 10-bit (1024-position) resolution. Both share similar electrical characteristics and memory features but differ in resolution and linearity specifications.
