X9455
Dual Two-wiper Digitally-Controlled
(XDCP) Potentiometer
The X9455 integrates 2 digitally controlled potentiometers
(XDCP), each one with dual wipers, on a monolithic CMOS
integrated circuit.
The digitally controlled potentiometer is implemented using
255 resistive elements in a series array. Between each
element are tap points connected to wiper terminals through
switches. The position of each wiper on the array is
controlled by the user through the U/D or 2-wire bus
interface. Each potentiometer wiper has associated with it
two volatile Wiper Counter Register (WCR) and each WCR
has associated with it 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. The contents of the default data
registers (DR0A0, DR0B0, DR1A0, DR1B0) are loaded into
the WCR on power up.
The DCP can be used as a four-terminal potentiometer in a
wide variety of applications including the programming of
bias voltages, window comparators, and three resistor
programmable networks.
