DESCRIPTION
The DS1806 is a six–channel digitally controlled solid–
state linear potentiometer. Each potentiometer is com-
prised of 63 equiresistive sections as illustrated in the
block diagram of Figure 1. Each potentiometer has
three terminals accessible to the user. These include
the high side terminals, H
X
, the wiper terminals, W
X
, and
the low–end terminals, L1–3 and L4–6. Potentiometers
1 through 3 share the same low–end terminal L1–3. And
likewise, potentiometers 4 through 6 share the low–end
terminal L4–6.
Each wiper’s position is selected via an 8–bit register
value. Communication and control of the device is ac-
complished via a 3–wire serial port interface. This inter-
face in conjunction with a cascade output allows the val-
ue of the device wiper settings to be read.
For multiple device and single processor environments,
the DS1806 can be cascaded or daisy chained. This
feature allows a single processor to control multiple de-
vices.
The DS1806 is available in 10K, 50K and 100K ohm ver-
sions and is specified over the industrial temperature
range. Packages for the device include 20–lead DIPs,
SOICs, and TSSOPs.
