X95840
Quad Digital Controlled Potentiometers (XDCP)
Low Noise/Low Power/I2C Bus/256 Taps
The X95840 integrates four digitally controlled
potentiometers (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
I2C bus interface. Each 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 contents of the four
DCP’s IVR to the corresponding WRs.
The DCPs can be used as three-terminal potentiometers or
as two-terminal variable resistors 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.
