Dual, 64-Position Nonvolatile Digital

Potentiometer with Buffered Outputs

General Description

Features

The DS3908 contains two nonvolatile digital poten-

tiometers with programmable-gain amplifiers buffering

the wiper outputs. The potentiometer position and

ꢀ Two 64-Position Linear Taper Potentiometers

ꢀ Integral Wiper Buffering Amplifiers with

Selectable Gains of 1V/V, 2V/V, or 4V/V

amplifier gain are controlled through an I C*-compati-

ꢀ 100kΩ Potentiometer End-to-End Resistance

ꢀ Low Potentiometer Temperature Coefficient

ꢀ Nonvolatile Wiper and Gain Storage

ble serial bus. The DS3908 operates in both 3.3V and

5V systems and features a write-protect pin that locks

the position of the potentiometers and gain registers. Up

to eight DS3908s can be placed on a single I C bus.
