Description

The X9400 integrates four digitally controlled potentiometers (XDCPs) on a monolithic CMOS integrated circuit.

The X9400 digitally 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 SPI serial bus interface. Each potentiometer has associated with it a volatile Wiper Counter Register (WCR) and four nonvolatile Data Registers (DR0-3) 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 through the switches.Power up recalls the contents of DR0 to the WCR.

The X9400 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.
