Description

The X9119 integrates a single digitally controlled potentiometer (XDCP) on a monolithic CMOS integrated circuit.

The X9119 digital controlled potentiometer is implemented using 1023 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. The X9119 potentiometer has associated with it a volatile Wiper Counter Register (WCR) and a four non-volatile 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
