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

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 low–end terminals, L1–3 and L4–6. Potentiometers

likewise, potentiometers 4 through 6 share the low–end

terminal L4–6.

TheDS1806isavailablein10K, 50Kand100Kohmver-

sions and is specified over the industrial temperature

range. Packages for the device include 20–lead DIPs,

SOICs, and TSSOPs.

Each wiper’s position is selected via an 8–bit register

value. Communication and control of the device is ac-
