Working Principles

The AD5231BRUZ50-REEL7 is a digital potentiometer that replaces traditional mechanical potentiometers. It consists of a series of resistive elements connected in a ladder-like structure. By digitally controlling the switches between these elements, the effective resistance can be adjusted.

The device communicates with a microcontroller or other digital circuitry through the I2C interface. The microcontroller sends commands to set the desired resistance value, which is stored in the non-volatile memory. The AD5231BRUZ50-REEL7 then adjusts its internal switches accordingly to achieve the specified resistance.
