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
