X9241YS

Digital Potentiometer 64POS 2KΩ Quad 20Pin SOIC

DESCRIPTION

The X9241 integrates four nonvolatile E2POT digitally controlled potentiometers on a monolithic CMOS microcircuit.

The X9241 contains four resistor arrays, each composed of 63 resistive elements. Between each element

and at either end are tap points accessible to the wiper elements. The position of the wiper element on the array is controlled by the user through the two-wire serial bus interface.
