X93156
Digitally Controlled Potentiometer
(XDCP)
The Intersil X93156 is a three-terminal digitally controlled
potentiometer (XDCP). The device consists of a resistor
array, wiper switches, a control section, and nonvolatile
memory. The wiper position is controlled by an Up/Down
interface.
The potentiometer is implemented by a resistor array
composed of 31 resistive elements and a wiper switching
network. The position of the wiper element is controlled by
the 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.
The device can be used as a three-terminal potentiometer or
as a two terminal variable resistor in a wide variety of
applications including the programming of bias voltages,
LCD brightness and contrast control as well as the
implementation of ladder networks.
