... Digital Potentiometer Solutions Low Power Applications Many applications are power sensitive. This is because they are battery powered or design goals on the power supply. Microchip Technology’s digital potentiometer families are low power, with the maximum I as low as 1 μA in some DD devices. This current is when the serial interface is inactive and a non-volatile memory write cycle is not active ...
