General Description
The DS1805 addressable digital potentiometer contains
a single 256-position digitally controlled potentiometer.
Device control is achieved through a 2-wire serial inter-
face. Device addressing is provided through three
address inputs that allow up to eight devices on a sin-
gle 2-wire bus. The exact wiper position of the poten-
tiometer 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 val-
ues: 10k
, 50k
, and 100k
. 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.
