PRELIMINARY
X9118
Dual Supply/Low Power/1024-Tap/2-Wire Bus
Single Digitally-Controlled (XDCP)
Potentiometer
DESCRIPTION
The X9118 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
2-wire bus interface. The potentiometer has
associated with it a volatile Wiper Counter Register
(WCR) and a 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.
