AD5291BRUZ-50-RL7

Digital Potentiometers Overview

The AD5291BRUZ-50-RL7 is a single-channel digital potentiometer featuring 256-position resolution and a nominal resistance of 50 kΩ. It operates on a single supply from +9 V to +33 V or dual supplies of ±9 V to ±16.5 V, with a logic supply range of 2.7 V to 5.5 V. The device includes nonvolatile memory for wiper setting retention and supports SPI-compatible serial interfaces. It provides maximum ±1% resistor tolerance error in performance mode and functions within an industrial temperature range of −40°C to +105°C.

Digital Potentiometers Feature Summary

• 256-position resolution with 50 kΩ nominal resistance
• Maximum ±1% end-to-end resistor tolerance error in performance mode
• Nonvolatile memory with power-on refresh capability
• SPI-compatible serial interface with wiper readback

Digital Potentiometers Applications

• Mechanical potentiometer replacement
• Instrumentation gain and offset adjustment
• Programmable voltage-to-current conversion
• Sensor calibration

Digital Potentiometers Procurement Notes

Verify the specific suffix RL7 against official documentation to confirm tape-and-reel packaging requirements. Confirm that the 50 kΩ variant matches the design resistance needs, as the series also offers 20 kΩ and 100 kΩ options. Ensure the logic supply voltage aligns with the 2.7 V to 5.5 V specification.

Digital Potentiometers Selection Notes

Select this component when high precision is required, utilizing the Resistor Performance Mode to achieve ±1% tolerance. Verify that the 256-position resolution meets the control granularity requirements, distinguishing it from the 1024-position AD5292 variant. Ensure the operating voltage range fits the system's single or dual supply constraints.

Digital Potentiometers Part Context

This part belongs to the AD5291/AD5292 family of digital potentiometers manufactured by Analog Devices Inc. The AD5291 specifically provides 256 positions, whereas the AD5292 offers 1024 positions. Both share similar electrical characteristics and package types but differ in resolution and associated code ranges for tolerance modes.

Digital Potentiometers Replacement Considerations

The AD5292BRUZ-50-RL7 serves as a functional substitute if higher 1024-position resolution is acceptable. Other variants like the AD5291BRUZ-20-RL7 or AD5291BRUZ-100-RL7 are available for different resistance values.
