Digital potentiometers, unlike mechanical ones, are much more damage resistant. DIGI POT 4 click is one of them. It's a perfect solution for modern designs that require precision calibration of set point thresholds, sensor trimming, LCD contrast adjustment, audio attenuation, an adjustable gain for amplifiers and offset trimming, etc.
DIGI POT 4 click
DIGI POT 4 click is a digitally controlled dual potentiometer, with the resistance of 10KΩ. It has a 10bit resolution which allows for a very smooth linear wiper positioning through 1024 steps. Digital wiper position can be controlled via SPI interface.
This click features a non-volatile durable EEPROM memory for storing the wiper position, which means that the device can restore its last position after the power on - just like its mechanical counterpart.
