DATASHEET X9258 FN8168 Rev 6.00 Low Noise/Low Power/2-Wire Bus/256 Taps Quad Digital Controlled December 15, 2011 Potentiometers (XDCP) The X9258 integrates 4 digitally controlled potentiometers Features (XDCP) on a monolithic CMOS integrated circuit. Four potentiometers in one package The digitally controlled potentiometer is implemented using 256 resistor taps/potentiometer................. 0.4% resolution 255 resistive elements in a series array. Between each element are tap points connected to the wiper terminal 2-wire serial interface through switches. The position of the wiper on the array is Wiper resistance, 40 typical V+ = 5V, V- = -5V controlled by the user through the 2-wire bus interface. Each Four nonvolatile data registers for each potentiometer potentiometer has associated with it a volatile Wiper Counter Register (WCR) and 4 non-volatile Data Registers Nonvolatile storage of wiper position (DR0:DR3) that can be directly written to and read by the Standby current <5A max (total package) user. The contents of the WCR controls the position of the wiper on the resistor array though the switches. Power-up Power supplies recalls the contents of DR0 to the WCR. -V = 2.7V to 5.5V CC - V+ = 2.7V to 5.5V The XDCP can be used as a three-terminal potentiometer - V- = -2.7V to -5.5V or as a two-terminal variable resistor in a wide variety of applications including control, parameter adjustments, and 100k, 50ktotal potentiometer resistance signal processing.
