QUAD 2.5K DIGITAL POTENTIOMETER, 2-WIRE SERIAL CONTROL INTERFACE, 64 POSITIONS, PDSO24, 4.40 MM, GREEN, PLASTIC, TSSOP-24
The X9408 integrates four digitally controlled potentiometers (XDCP) on a monolithic CMOS integrated circuit. The digital controlled potentiometer is implemented using 63 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 four non-volatile Data Registers that can be directly written to and read by the user. The contents of the WCRcontrols the position of the wiper on the resistor array though the switches. Poweru p 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.
