DESCRIPTION
The X9111 integrates a single digitally controlled
potentiometer (XDCP) on a monolithic CMOS
integrated circuit.
The digital controlled potentiometer is implemented
using 1023 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 non-volatile 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.
