Description
The MAX5432–MAX5435 nonvolatile, linear-taper, digital potentiometers perform the function of a mechanical potentiometer, but replace the mechanics with a simple 2-wire serial interface. Each device performs the same function as a discrete potentiometer or a variable resistor and has 32 tap points.

The MAX5432–MAX5435 feature an internal, nonvolatile, electrically erasable programmable read-only memory (EEPROM) that returns the wiper to its previously stored position at power-up. The fast-mode I²C-compatible serial interface allows communication at data rates up to 400kbps, minimizing board space and reducing interconnection complexity. Each device is available with multiple factory-preset I²C addresses (see the Ordering Information/Selector Guide in the full data sheet).

Use the MAX5432–MAX5435 in applications requiring digitally controlled resistors. Two resistance values are available (50kΩ and 100kΩ) in a voltage-divider or variable resistor configuration. The nominal resistor temperature coefficient is 35ppm/°C end-to-end, and only 5ppm/°C ratiometric, making the devices ideal for applications requiring a low-temperature-coefficient variable resistor such as low-drift, programmable-gain amplifier circuit configurations.

The MAX5432/MAX5433 are available in a 3mm x 3mm 8-pin TDFN package and the MAX5434/MAX5435 are available in a 6-pin thin SOT23 package. The MAX5432–MAX5435 are specified over the extended (-40°C to +85°C) temperature range.

An evaluation kit is available:  MAX5432EVKIT
