Parallel digital potentiometers

akarko01 on Mar 11, 2018

Hello,

In my application I will need four digital potentiometers (AD5272/AD5274), which I will connect parallel. Could you tell if that is possible? If it is possible, you can give instructions how I will manage this.

Thank you,

Andreas Karkotis

Hi Andreas,

Is the concern the fact that the 3-state ADDR pin only gives you 3 I2C addresses? You could either use an I2C multiplexer, or either LTC4316 or LTC4317 Address Translators:
