ISL22326

Dual Digitally Controlled Potentiometers (XDCP™)

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.
