Loads Saved Wiper Position on Power Up. • Standby Current < 5µA Max • 50K Ω, 100KΩ versions of End to End Pot Resistance • 100 yr. Data Retention • Endurance: 100,000 Data Changes per Bit per Register • 24-Lead SOIC, 16-Lead CSP (Chip Scale Pack- age), 24-Lead TSSOP • Low Power CMOS • Power Supply VCC = 2.7V to 5.5V DESCRIPTION The X9269 integrates 2 digitally controlled potentiometer (XDCP) on a monolithic CMOS integrated circuit. The digital 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 a four nonvolatile 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. Powerup recalls the contents of the default Data Register (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.
