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 AD7715 consumes only 450 μA, leaving 3 mA available for
the rest of the transmitter. Figure 17 shows a block diagram of a
smart transmitter which includes the AD7715. Not shown in
Figure 17 is the isolated power source required to power the
front end.
