DESCRIPTION
The Xicor 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 implemetnation of ladder networks.
