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 I
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.
