X9241A
Low Power/2-Wire Serial Bus
Data Sheet
September 15, 2005
FN8164.1
Quad Digitally Controlled Potentiometer
(XDCP鈩?
The X9241A integrates four digitally controlled
potentiometers (XDCP) on a monolithic CMOS integrated
microcircuit.
The digitally controlled potentiometer is implemented using
63 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 4 nonvolatile Data Registers
(DR0:DR3) 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 through the switches. Power up
recalls the contents of 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.
