描述 Description

Non-volatile electronic potentiometerThe BU9831 / BU9831F is a non-volatile electronic potentiometer with an internal 2k bit EEPROM. The resistance
value can be set by means of serial communications, and because the product contains an internal memory, conditions can be retained. In addition, the 2k bit memory capacity enables digital data to be stored in the memory.
