DESCRIPTION
The DS1803 is an addressable device having two inde-
pendently controlled potentiometers. Each potentiome-
ter’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. Addres-
sing capability, when operating in a bus topology, allows
up to eight devices to be controlled by the serial inter-
face. 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 val-
ues: 10K
, 50K
, and 100K
, and is specified over the
industrial temperature range.
