FEATURES  
DESCRIPTION  
• Quad–Four separate potentiometers  
• 256 resistor taps/pot–0.4% resolution  
• 2-Wire Serial Interface for write, read, and  
transfer operations of the potentiometer  
The X9259 integrates  
potentiometer (XDCP) on  
integrated circuit.

digitally controlled  
monolithic CMOS  
a
The digital controlled potentiometer is implemented  
using 255 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 a four  
nonvolatile 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.
