General Description
The DS3908 contains two nonvolatile digital poten-
tiometers with programmable-gain amplifiers buffering
the wiper outputs. The potentiometer position and
amplifier gain are controlled through an I
2
C*-compati-
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
2
C bus.
