ISL22326
Dual Digitally Controlled Potentiometers (XDCP™)
September 9, 2015
FN6176.3
Low Noise, Low Power, I2C™ Bus, 128 Taps
The ISL22326 integrates two digitally controlled potentiometers
(XDCP) and non-volatile memory on a monolithic CMOS
integrated circuit.
The digitally controlled potentiometers are 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. Each 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 two
DCP’s IVR to the corresponding WRs.
The DCPs can be used as three-terminal potentiometers or
as two-terminal variable resistors in a wide variety of
applications including control, parameter adjustments, and
signal processing.
