Digitally Controlled Potentiometer
(XDCP™)
The Intersil ISL90462 is a digitally controlled potentiometer
(XDCP). Configured as a variable resistor, the device
consists of a resistor array, wiper switches, a control section,
and volatile memory. The wiper position is controlled by a 2-
pin Up /Down interface.
The potentiometer is implemented by a resistor array
composed of 31 resistive elements and a wiper switching
network. Between each element and at either end are tap
points accessible to the wiper terminal. The position of the
wiper element is controlled by the CS and U/D inputs.
The device can be used in a wide variety of applications
including:
• LCD contrast control
• Parameter and bias adjustments
• Industrial and Automotive Control
• Transducer adjustment of pressure, temperature, position,
chemical, and optical sensors
• Laser Diode driver biasing
• Gain control and offset adjustment

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
