ISL22316WMUEP

Single Digitally Controlled Potentiometer (XDCP™)

Low Noise, Low Power I2C® Bus, 128 T aps

The ISL22316WMUEP integrates a single digitally controlled

potentiometer (DCP) and non-volatile memory on a

monolithic CMOS integrated circuit.

The digitally controlled potentiometer is imple mented with a

combination of resistor elements and CMOS switches. The

position of the wipers are controlled by the user through the

I2C bus interface. The potentiometer has an associated

volatile Wiper Register (WR) and a non-volatile Initial Value

user. The contents of the WR controls the position of the

wiper. At power-up, the device recalls the contents of the

DCP’s IVR to the WR.

The DCP can be used as a three-terminal potentiometer or

as a two-terminal variable resistor in a wide vari ety of

applications including control , parameter adjustments and

signal processing.

Device Information

The specifications for an Enhanced Product (EP) device are

defined in a Vendor Item Drawing (VID), which is controlled

by the Defense Supply Center in Columbus (DSCC).

“Hot-links” to the applicable VID and other supporting

application information are provided on our website.
