Non-volatile electronic potentiometer
BU9831 / BU9831F
The 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, condi-
tions can be retained.
In addition, the 2k bit memory capacity enables digital data to be stored in the memory.
