DESCRIPTION
The DS1667 is a dual–solid state potentiometer that is
adjustable by digitally selected resistive elements.
Each potentiometer is composed of 256 resistive ele-
ments. Between each resistive section of each poten-
tiometer are tap points accessible to the wiper. The po-
sition of the wiper on the resistive array is set by an 8–bit
register that controls which tap point is connected to the
wiper output. Each 8–bit register can be read or written
by sending or receiving data bits over a 3–wire serial
port. In addition, the resistors can be stacked such that
a single potentiometer of 512 sections results. When
two separate potentiometers are used, the resolution of
the DS1667 is equal to the resistance value divided by
256. When the potentiometers are stacked end to end,
the resistance value is doubled while the resolution re-
mains the same. The DS1667 also contains two high
gain wide bandwidth operational amplifiers. Each am-
plifier has both the inverting and non-inverting inputs
and the output available for user configuration. The op-
erational amplifiers can be paired with the resistive ele-
