DESCRIPTION
The DS1267 consist of two digitally controlled solid–
state potentiometers. Each potentiometer is composed
of 256 resistive sections. Between each resistive sec-
tion and both ends of the potentiometer are tap points
which are accessible to the wiper. The position of the
wiper on the resistive array is set by an 8–bit value that
controls which tap point is connected to the wiper output.
Communication and control of the device is accom-
plished via a 3–wire serial port interface. This interface
allows the device wiper position to be read or written.
Both potentiometers can be connected in series (or
stacked) for an increased total resistance with the same
resolution. For multiple device–single processor envi-
ronments, the DS1267 can be cascaded or daisy
chained. This feature provides for control of multiple
devices over a single 3–wire bus.
