Rev 3.00
August 14, 2015 Single Digitally Controlled Potentiometer (XDCPв„ў) Low Noise, Low Power I2Cв„ў
Bus, 128 Taps
The ISL22316 integrates a single digitally controlled
potentiometer (DCP) and non-volatile memory on a
monolithic CMOS integrated circuit. Features 128 resistor taps 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
I2C 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. I2C serial interface
