X9258
Low Noise/Low Power/2-Wire Bus/256 Taps
Quad Digital Controlled Potentiometers
(XDCP)
The X9258 integrates 4 digitally controlled potentiometers
(XDCP) 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 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 non-volatile 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 though 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.
