DS1805
Addressable Digital Potentiometer
6
_____________________________________________________________________
Detailed 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 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: 10k
, 50k, and
100k
. The DS1805 specified over the industrial temper-
ature range. The DS1805 is provides a low-cost alterna-
tive for designs based on the DS1803, but require only a
single potentiometer.
Device Operation
The DS1805 is an addressable, digitally controlled
device that has a single 256-position potentiometer.
Figure 1 shows a block diagram of the part.
Communication and control of the device is accom-
plished through a 2-wire serial interface that has SDA
and SDL signals. Device addressing is attained using
the device chip-select inputs A0, A1, and A2.
