DESCRIPTION
The
potentiometer (XDCP) on a monolithic CMOS
integrated circuit.
X9259
integrates

digitally
controlled
The digital controlled potentiometer is implemented
using 255 resistive elements in a series array. Between
each element are tap points connected to the wiper
terminal through switches. The position of the wiper on
the array is controlled by the user through the 2-Wire
bus interface. Each potentiometer has associated with
it a volatile Wiper Counter Register (WCR) and a four
nonvolatile Data Registers that can be directly written
to and read by the user. The contents of the WCR
controls the position of the wiper on the resistor array
though the switches. Powerup recalls the contents of
the default Data Register (DR0) to the WCR.
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.
