DESCRIPTION
The DS1803 Addressable Dual Digital Potentiometer is an addressable device having two independently
controlled potentiometers. Each potentiometer’s wiper can be set to one of 256 positions. Device control
is achieved via a 2-wire serial interface having a data I/O terminal and a clock input terminal. Device
addressing is provided through three chip select input terminals and correct communication protocol.
Addressing capability, when operating in a bus topology, allows up to eight devices to be controlled by
the serial interface. The exact wiper position of each potentiometer can be written or read. The DS1803
is available in a 16-pin DIP, 16-pin SOIC 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.
