DATASHEET X9250 FN8165 Rev.3.00 Low Noise/Low Power/SPI Bus/256 Taps Quad Digitally Controlled August 29, 2006 Potentiometers (XDCP) FEATURES DESCRIPTION Four potentiometers in one package The X9250 integrates 4 digitally controlled 256 resistor taps/pot - 0.4% resolution potentiometers (XDCP) on a monolithic CMOS SPI serial interface integrated circuit. Wiper resistance, 40 typical V = 5V CC The digitally controlled potentiometer is implemented Four nonvolatile data registers for each pot using 255 resistive elements in a series array. Nonvolatile storage of wiper position Between each element are tap points connected to the Standby current < 5A max (total package) wiper terminal through switches. The position of the Power supplies wiper on the array is controlled by the user through the V = 2.7V to 5.5V CC SPI bus interface. Each potentiometer has associated V+ = 2.7V to 5.5V with it a volatile Wiper Counter Register (WCR) and 4 V = -2.7V to -5.5V nonvolatile Data Registers (DR0:DR3) that can be 100k, 50k total pot resistance directly written to and read by the user. The contents High reliability of the WCR controls the position of the wiper on the Endurance 100,000 data changes per bit per resistor array though the switches. Power up recalls register the contents of DR0 to the WCR. Register data retention - 100 years 24 Ld SOIC, 24 Ld TSSOP The XDCP can be used as a three-terminal Dual supply version of X9251 potentiometer or as a two-terminal variable resistor in Pb-free plus anneal available (RoHS compliant) a wide variety of applications including control, parameter adjustments, and signal processing.
