GENERAL DESCRIPTION
The AD5273 is a 64-position, One-Time-Programmable (OTP) digital potentiometer4 that employs fuse link technology to achieve the permanent program setting. This device performs the same electronic adjustment function as most mechanical trimmers and variable resistors. It allows unlimited adjustments before permanently setting the resistance values. The AD5273 is programmed using a 2-wire, I2C compatible digital control. During the write mode, a fuse blow command is executed after the final value is determined, therefore freezing the wiper position at a given setting (analogous to placing epoxy on a mechanical trimmer).
