ISL22319
Single Digitally Controlled Potentiometer (XDCP)
Low Noise, Low Power, I2C Bus,
128 Taps, Wiper Only
The ISL22319 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
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 content of the
DCP’s IVR to the WR.
The DCP can be used as a voltage divider in a wide variety
of applications including control, parameter adjustments, AC
measurement and signal processing.
