This is a 7 bit digital potentiometer with non-volatile memory. It features an output range of up to 15.5V. Programming is done through an I2C interface, with operating speeds of up to 400kHz.

A digital potentiometer device has three main functional blocks. These are the serial interface, the system control and the resister network.

Welcome to the interfacing to digital potentiometers web presentation. We will cover material that should give you a better understanding of the different interfaces that are used to interface to digital potentiometers and some special features that Microchip supports on the serial interface.
