DESCRIPTION
The Intersil X93256 is a dual digitally controlled
potentiometer (XDCP). The device consists of two
resistor arrays, wiper switches, a control section, and
nonvolatile memory. The wiper positions are controlled
by individual Up/Down interfaces.
A potentiometer is implemented by a resistor array
composed of 31 resistive elements and a wiper switching
network. The position of each wiper element is controlled
by a set of independent CS, U/D, and INC inputs. The
position of the wiper can be stored in nonvolatile memory
and then be recalled upon a subsequent power-up
operation.
Each potentiometer is connected as a three-terminal
variable resistor and can be used in a wide variety of
applications including:
– Bias and Gain Control
– LCD Contrast 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.
