General Description
The DS4301 is a single 32-position linear digital poten-
tiometer with 200k
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 200k
end-
to-end resistance are especially suited for portable,
battery-powered applications such as cellular tele-
phones and PDAs.
