Single Digitally Controlled Potentiometer (XDCP™)
ISL22316WMUEP
Data Sheet December 17, 2007
Low Noise, Low Power I2C® Bus, 128 Taps
The ISL22316WMUEP integrates a single digitally controlled
potentiometer (DCP) and non-volatile memory on a
monolithic CMOS integrated circuit.
The digitally controlled potentiometer is implemented with a
combination of resistor elements and CMOS switches. The
position of the wipers are controlled by the user through the
2
I
C bus interface. The potentiometer has an associated
volatile Wiper Register (WR) and a non-volatile Initial Value
Register (IVR) that can be directly written to and read by the
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 variety 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.
