X9241AWPIZ

数字电位计 IC X9241AWPIZ 10K QD EEPOTTM POT CMOS P

Quad Digital Controlled Potentionmeters (XDCP™) Non-Volatile/Low  Power/2-Wire/64 Taps

The X9241AWPIZ X9241A integrates four digitally controlled  potentiometers (XDCP) on a monolithic CMOS integrated  microcircuit.

The 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 2-wire bus interface. Each  potentiometer has associated with it a volatile Wiper Counter  Register (WCR) and 4 nonvolatile Data Registers  (DR0:DR3) 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.
