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 I2C-compatible
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 I2C bus.
Applications
Pin-Diode Biasing
