The MAX5128ELA+T is a 128-tap linear taper digital potentiometer in 8 pin μDFN package. The device performs the same function as a discrete potentiometer or variable resistor. An integrated non-volatile memory recalls the programmed wiper position of the digital potentiometer. A simple 2-wire up/down interface programs the wiper position. It is ideally used for backlight adjustment, bias settings for radio and LED bias adjustments.
