Description

The DS4301 is a single 32-position linear digital poten-tiometer with 200kΩ end-to-end resistance. The wiper setting is stored in EEPROM, so the DS4301 powers up with the last stored setting. The position of the wiper is controlled through a simple three-terminal increment/decrement interface. The DS4301 is ideal for white LED backlight brightness control. Its 8-pin µSOP package, 2.4V to 5.5V supply range, and 200kΩ end-to-end resistance are especially suited for portable, battery-powered applications such as cellular tele-phones and PDAs.
