DESCRIPTION
The DS1803 addressable dual digital potentiometer features two independently controlled 256-position
potentiometers. Device control is achieved through a 2-wire serial interface. Three address pins allow up
to 8 DS1803’s to share the same 2-wire interface. The exact wiper position of each potentiometer can be
written or read. The DS1803 is available in a 16-pin DIP, 16-pin SO, and 14-pin TSSOP package. The
device is available in three standard resistance values: 10k, 50k, and 100k and is specified over the
industrial temperature range.
