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.

Applications

•

Portable LCD backlight adjustment devices for notebook computers, and other sound adjustment devices for sets

Features

•

1) Internal 2k bit EEPROM

2) 100kΩ (1kΩ × 100 steps) electronic potentiometer

3) Data in memory is automatically read when power supply is turned on, and resistance value is set.

4) Resistance value can be set using serial communications.

5) Low current consumption

When operating: 3mA (max.)

In standby mode: 200µA (max.)

Absolute maximum ratings (Ta = 25°C)
