The DS4301 is a single 32-position linear digital potentiometerwith 200kΩ end-to-end resistance. The wipersetting is stored in EEPROM, so the DS4301 powers upwith the last stored setting. The position of the wiper iscontrolled through a simple three-terminalincrement/decrement interface. The DS4301 is ideal forwhite LED backlight brightness control. Its 8-pin μSOPpackage, 2.4V to 5.5V supply range, and 200kΩ endto-end resistance are especially suited for portable,battery-powered applications such as cellular telephonesand PDAs.ApplicationsWhite LED Backlight Brightness ControlPortable Battery-Powered Devices such as PDAsand Cellular PhonesAny Application that Requires a Small, Low-CostNV Potentiometer
