X9259 Overview
DATASHEET X9259 Single Supply/Low Power/256-Tap/2-Wire Bus Quad Digitally-Controlled (XDCP™) Potentiometers FN8169 Rev 6.00 December 12, 2014 The X9259 integrates four digitally controlled potentiometers (XDCP) on a monolithic CMOS integrated circuit. The digitally controlled potentiometers are implemented with a bination of resistor elements and CMOS switches. The position of the wipers are controlled by the user...
