Single Digitally Controlled Potentiometer
(XDCP™)
The Intersil X9314 is a solid state nonvolatile potentiometer and
is ideal for digitally controlled resistance trimming.
The X9314 is a resistor array composed of 31 resistive
elements. Between each element and at either end are tap
points accessible to the wiper element. 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 XDCP can be used as a three-terminal potentiometer or
as a two-terminal variable resistor in a wide variety of
applications including control, parameter adjustments, and
signal processing.
