ISL95811
Single Digitally Controlled Potentiometer (XDCP)
Data Sheet
October 6, 2008
I2C Bus, 256 Taps, 5 Bytes General
Purpose Memory, Low Noise, Low Power
The ISL95811 integrates a digitally controlled potentiometer
(XDCP) 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 wiper is 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 content 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 three-terminal potentiometer or as
two-terminal variable resistor in a wide variety of applications
including control, parameter adjustments and signal
processing.
