Smart Transmitters
Another area where the low power, single supply, three-wire
interface capabilities is of benefit is in smart transmitters. Here,
the entire smart transmitter must operate from the 4 mA to
20 mA loop. Tolerances in the loop mean that the amount of
current available to power the transmitter is as low as 3.5 mA.
The AD7714 consumes only 500
A, leaving 3 mA available for
the rest of the transmitter. Figure 16 shows a block diagram of a
smart transmitter which includes the AD7714. Not shown in
Figure 16 is the isolated power source required to power the
front end.
