The MAX5460MAX5468 linear-taper digital potentiometers perform the same function as a mechanical potentiometer or a variable resistor. These devices consist of a fixed resistor and a wiper contact with 32-tap points that are digitally controlled through a 2-wire serial interface. The MAX5462/MAX5465/MAX5468 are configured as potentiometers. The rest of the devices in this family are configured as variable resistors. See Pin Configurations for part functionality.
