AD5270BRMZ-50-RL7

Digital Potentiometers Overview

The AD5270BRMZ-50-RL7 is a single-channel digital rheostat featuring 1024 tap positions and a nominal resistance of 50 kΩ. It operates on a single supply voltage ranging from 2.7 V to 5.5 V or dual supplies of ±2.5 V to ±2.75 V. The device incorporates nonvolatile memory allowing for 50 programmable wiper settings that persist across power cycles. It utilizes an SPI-compatible serial interface for control and readback, housed in a compact 10-lead MSOP package.

Digital Potentiometers Feature Summary

• 1024-position resolution with guaranteed ±1% resistor tolerance error
• 50-times programmable (50-TP) nonvolatile memory for wiper position retention
• SPI-compatible serial interface supporting data rates up to 50 MHz
• Low supply current of 1 µA and extended industrial temperature range (-40°C to +125°C)

Digital Potentiometers Applications

• Mechanical rheostat replacements
• Op-amp variable gain control
• Instrumentation gain and offset adjustment
• Programmable filters and time constants

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging type and tape/reel specifications. Confirm RoHS compliance status through official datasheets or component markings before integration into production designs.

Digital Potentiometers Selection Notes

Select this model for applications requiring precise analog resistance control without mechanical wear. Ensure the system voltage falls within the 2.7 V to 5.5 V single-supply range. Verify that the 50 kΩ nominal resistance aligns with the target circuit impedance requirements.

Digital Potentiometers Part Context

This component belongs to the AD5270/AD5271 family of digital rheostats. The AD5270 variant specifically provides 10-bit (1024-position) resolution, distinguishing it from the 8-bit AD5271. The BRMZ suffix indicates the commercial temperature grade and MSOP package style.

Digital Potentiometers Replacement Considerations

Direct substitutes include other AD5270 variants with different resistance values such as AD5270BRMZ-20 or AD5270BRMZ-100. For lower resolution needs, the AD5271 series may be considered if pin compatibility is maintained.
