INDUSTRIAL ANALOG OUTPUT APPLICATION
Many industrial control applications have requirements for
accurately controlled current output signals, and the AD5410/
AD5420 are ideal for such applications. Figure 53 shows the
AD5410/AD5420 in a circuit design for an output module
specifically for use in an industrial control application. The
design provides for a current output. The module is powered
from a field supply of 24 V. This supplies AV
transient overvoltage protection, transient voltage suppressors
(TVS) are placed on both the I
A 24 V TVS is placed on the I
placed on the field supply input. For added protection, clamping
diodes are connected from the I
power supply pins. Isolation between the AD5410/AD5420 and
the backplane circuitry is provided with the

The internally generated digital power supply of the AD5410/
AD5420 powers the field side of the digital isolators, removing
the need to generate a digital power supply on the field side of
the isolation barrier. The AD5410/AD5420 digital supply out-
put supplies up to 5 mA, which is more than enough to supply
the 2.8 mA requirement of the ADuM1400 and ADuM1200
operating at a logic signal frequency of up to 1 MHz. To reduce
the number of isolators required, nonessential signals such as
CLEAR can be connected to GND and FAULT , and SDO can be
left unconnected, reducing the isolation requirements to just
three signals. Doing so, however, disables the fault alert features
of the part.
