DS1803Z-100-TR Datasheet

Addressable Dual Digital Potentiometer


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: 10kΩ, 50kΩ, and 100kΩand is specified over the industrial temperature range.
