AD5272BRMZ-50-RL7

Digital Potentiometers Overview

The AD5272BRMZ-50-RL7 is a single-channel digital rheostat featuring 1024-position resolution and a nominal resistance of 50 kΩ. It utilizes an I²C-compatible interface for control and includes 50-times programmable (50-TP) nonvolatile memory to retain wiper settings across power cycles. The device guarantees a maximum ±1% end-to-end resistor tolerance error, ensuring precision in open-loop applications. It operates on a single supply from 2.7 V to 5.5 V or dual supplies of ±2.5 V to ±2.75 V. Packaged in a compact 10-lead MSOP format, it supports fast-mode data transfer up to 400 kbps.

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure compatibility with the target system's I²C bus voltage levels and address configuration requirements before integration.

Digital Potentiometers Selection Notes

Select this component when precise, digitally adjustable resistance is required without external calibration. The 50-TP memory allows for permanent setting retention, eliminating the need for continuous power to maintain the resistance value. Verify that the 50 kΩ nominal resistance aligns with the circuit's impedance matching and current handling requirements.

Digital Potentiometers Part Context

This part belongs to the AD5272/AD5274 family of digital rheostats manufactured by Analog Devices. The AD5272 variant specifically offers 1024 positions, whereas the AD5274 provides 256 positions. Both share similar electrical characteristics and interface protocols but differ in resolution and available nominal resistance values.
