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 100kΩ and is specified over the industrial temperature range. * 3V or 5V Operation * Ultra-Low Power Consumption * Two Digitally Controlled, 256- Potentiometers * 14-Pin TSSOP (173 mil) and 16- mil) Packaging Available for Surface- Applications * Addressable Using 3 Address * 2-Wire Serial Interface * Operating Temperature Range: * Industrial: -40°C to +85°C * Standard Resistance Values:\x02 * DS1803-010 10kΩ * DS1803-050 50kΩ * DS1803-100 100kΩ
