MAX5422ETA+T (MAXIM INTEGRATED PRODUCTS)

The MAX5422ETA+T from Maxim Integrated Products is a 256-tap, non-volatile, SPI interface digital potentiometer in 8 pin TDFN package. This digital potentiometer performs the function of a mechanical potentiometer but replaces mechanics with a simple 3-wire SPI compatible digital interface. It performs same function as a discrete potentiometer or variable resistor and has 256 tap points. The 3-wire SPI-compatible serial interface allows communication at data rates up to 5MHz, it minimizes board space and reduce interconnection complexity in many applications. It is ideal for applications requiring a low temperature coefficient variable resistor such as low drift, programmable gain amplifier circuit configurations. Typical applications mechanical potentiometer replacement, low drift programmable gain amplifiers, audio volume control, liquid crystal display (LCD) contrast control and low drift programmable filters.
