X9118 Dual Supply/Low Power/1024-Tap/2-Wire Bus Data Sheet April 9, 2014 FN8161.5 Single Digitally-Controlled (XDCP) Features Potentiometer 1024 resistor taps 10-bit resolution The X9118 is a single digitally controlled potentiometer 2-wire serial interface for write, read and transfer (XDCP) on a monolithic CMOS integrated circuit. operations of the potentiometer The digital controlled potentiometer is implemented using Wiper resistance, 40 typical 5V 1023 resistive elements in a series array. Between each Four non-volatile data registers for each potentiometer element are tap points connected to the wiper terminal through switches. The position of the wiper on the array is Non-volatile storage of multiple wiper positions controlled by the user through the 2-wire bus interface. The Power on recall: Loads saved wiper position on power-up potentiometer has associated with it a volatile Wiper Counter Register (WCR) and a four non-volatile Data Registers that Standby current < 15A Max can be directly written to and read by the user. The contents : 2.7V to 5.5V operation System V CC of the WCR controls the position of the wiper on the resistor Analog V+/V-: -5V to +5V array though the switches. Power-up recalls the contents of the default data register (DR0) to the WCR. 100k end-to-end resistance The XDCP can be used as a three-terminal potentiometer or Endurance: 100,000 data changes per bit per register as a two terminal variable resistors in a wide variety of 100 years data retention applications including control, parameter adjustments, and signal processing. 14 Ld TSSOP Low power CMOS Pb-free (RoHS compliant) Ordering Information POTENTIOMETER TEMP PART NUMBER PART VCC LIMITS ORGANIZATION RANGE PACKAGE PKG.
