Overview

The AD5171BRJZ50-R2 is a 64-position, one-time programmable (OTP) digital potentiometer2 that uses fuse link technology to achieve the memory retention of the resistance setting function. OTP is a cost-effective alternative over the EEMEM approach for users who do not need to reprogram new memory settings in the digital potentiometer. This device performs the same electronic adjustment function as most mechanical trimmers and variable resistors. The AD5171BRJZ50-R2 is programmed using a 2-wire, I2C®-compatible digital control. It allows unlimited adjustments before permanently setting the resistance value. During the OTP activation, a permanent fuse blown command is sent after the final value is determined, freezing the wiper position at a given setting (analogous to placing epoxy on a mechanical trimmer).

1Applies to 5 kΩ parts only.2 The terms digital potentiometer and RDAC are used interchangeably.
