MAXIM INTEGRATED / ANALOG DEVICES MAX5422ETAT Digital Potentiometer

The MAX5422ETA+T from Maxim Integrated is a 256-tap, non-volatile, digitally controlled potentiometer in an 8-pin TDFN package. It simulates a mechanical potentiometer by replacing manual adjustment with a simple 3-wire SPI-compatible digital interface, supporting communication up to 5MHz. The device features 256 tap points, a resistance of 50kΩ end-to-end with a low temperature coefficient, and internal EEPROM to store the wiper position for consistent startup. It operates from a single supply voltage of 2.7V to 5.25V over a temperature range of -40°C to 85°C. The device is ideal for applications such as replacing mechanical potentiometers, low drift programmable gain amplifiers, audio volume control, LCD contrast adjustment, and programmable filters. It offers low static current consumption, fast wiper settling time, and precise linear taper performance.
