Nonvolatile, 32-Position Digital Potentiometer

General Description

Features

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

♦ Single, 32-Position, 200kΩ Linear Nonvolatile (NV)

Potentiometer Ideal for Battery-Powered

Applications

♦ Three-Terminal Increment/Decrement Interface to

controlled through

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.

Adjust Wiper Position

♦ Wide Voltage Supply Range (2.4V to 5.5V)

♦ Command-Initiated NV Wiper Storage

♦ Operates Over the Industrial Temperature Range

(-40°C to +85°C)

♦ Available in 8-Pin µSOP
