The AD8400ARZ50-REEL with Digital Potentiometer IC from Analog Devices is a single 8-bit digital potentiometer IC that offers reliable and adjustable resolution control with 50K Ohms of resistance in a compact surface mount package. It is an ideal solution for applications requiring a variable analog signal, such as motion control and motor control, as well as in audio and power management applications. The potentiometer features I2C compatible and SPI-compatible serial interface, allowing for non-volatile remote setting, adjusting, or canceling of settings. This makes it suitable for use in applications where precise settings of physical parameters, such as position, speed, brightness and audio level, need to be configured. Other features include a maximum supply voltage of 5.5V, low operating current, and wiper settings with a resolution of 26 separate steps from 0-50K Ohm with 10µA of max leakage current.
