DESCRIPTION
The X9271 integrates a single, digitally controlled
potentiometer (XDCP) on a monolithic CMOS
integrated circuit.
The digitally controlled potentiometer is implemented by
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 SPI bus
interface. The potentiometer has associated with it a
volatile Wiper Counter Register (WCR) and four
nonvolatile data registers that can be directly written to
and read by the user. The contents of the WCR control
the position of the wiper on the resistor array though the
switches. Power-up 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.
