X9119
Single Supply/Low Power/1024-Tap/2-Wire Bus

FN8162.4
Single Digitally-Controlled (XDCP™)
Potentiometer
The X9119 integrates a single digitally controlled
potentiometer (XDCP™) on a monolithic CMOS integrated
circuit.
The digital controlled potentiometer is implemented using
1023 resistive elements in a series array. Between each
element are tap points connected to the wiper terminal
through switches. The position of the wiper on the array is
controlled by the user through the 2-wire bus interface. The
potentiometer has associated with it a volatile Wiper Counter
Register (WCR) and a four non-volatile Data Registers that
can be directly written to and read by the user. The contents
of the WCR controls the position of the wiper on the resistor
array though the switches. Powerup recalls the contents of
the default data register (DR0) to the WCR.
The XDCP™ can be used as a three-terminal potentiometer
or as a two terminal variable resistor in a wide variety of
applications including control, parameter adjustments, and
signal processing.

NOTE: These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach
materials, and 100% matte tin plate plus anneal (e3 termination finish, which is 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.
