Low Noise/Low Power/I
The ISL90810 integrates a digitally controlled potentiometer
(XDCP) 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
I
Wiper Register (WR) that can be directly written to and read
by the user. The contents of the WR controls the position of
the wiper. When powered on the ISL90810’s wiper will
always commence at mid-scale (128 tap position).
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.
