The DS4301 is a single 32-position linear digital potentiometer 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 telephones and PDAs.
The DS4301 is a single nonvolatile digital potentiometer featuring an end-to-end resistance of 200kΩ and operating over a wide supply voltage range from 2.4V to 5.5V. The device utilizes a simple three-terminal interface (CS, INC, U/D) to control the wiper position, which is stored in internal EEPROM for retention after power loss.
