1. Describe

Non-volatile/low power consumption/2 wires/64 taps X9241AWP integrates four digital controls Potentiometer (XDCP) integrated on monolithic CMOS Microcircuit. Use CNC potentiometer 63 resistance elements are arranged in series. Between each The element is the tap point connected to the wiper terminal Pass the switch. The position of the wiper on the array is Controlled by the user through the 2-wire bus interface. Each Potentiometer associated with volatile tap counter Register (WCR) and 4 non-volatile data registers (DR0:DR3) can be read and written directly user. WCR content control By switching the wiper on the resistor array. Toll Recall the contents of DR0 to WCR. XDCP can be used as a three-terminal potentiometer or As various types of variable resistors at both ends Applications include control, parameter adjustment and Signal processing.
