ISL95810
Single Digitally Controlled Potentiometer (XDCP鈩?
Data Sheet
October 7, 2005
FN8090.1
Low Noise, Low Power I
2
C Bus, 256 Taps
The ISL95810 integrates a digitally controlled potentiometer
(XDCP) 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
2
C
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鈥檚 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.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with both SnPb
and Pb-free soldering operations. Intersil Pb-free products are MSL classified
at Pb-free peak reflow temperatures that meet or exceed the Pb-free
requirements of IPC/JEDEC J STD-020.
