The DS1805 addressable digital potentiometer contains
a single 256-position digitally controlled potentiometer.
Device control is achieved through a 2-wire serial interface.
Device addressing is provided through three
address inputs that allow up to eight devices on a single
2-wire bus. The exact wiper position of the potentiometer
can be written or read. The DS1805 is
available in 16-pin SO and 14-pin TSSOP packages.
The device is available in three standard resistance values:
10kΩ, 50kΩ, and 100kΩ. The DS1805 is specified
over the industrial temperature range. The DS1805
provides a low-cost alternative for designs based on
the DS1803, but require only a single potentiometer.
