Process Current Input with Offset.
Figure 18 shows an iso-
lator receiver which translates a 4-20 mA process current signal
into a 0 V to +10 V output. A 1 V to 5 V signal appears at the
isolator’s output, and a –1 V reference applied to output LO
provides the necessary level shift (in multichannel applications,
the reference can be shared by all channels). This technique is
often useful for getting offset with a follower-type output buffer.

Figure 18. Process Current Input Isolator with Offset
The circuit as shown requires a source compliance of
at least
5 V, but if necessary that can be reduced by using a lower value
of current-sampling resistor and configuring the input amplifier
for a small gain.
High-Compliance Current Source.
In Figure 19, an isolator
is used to sense the voltage across current-sensing resistor R to
allow direct feedback control of a high-voltage transistor or FET
used as a high-compliance current source. Since the isolator has
virtually no response to dc common-mode voltage, the closed-
loop current source has a static output resistance greater than
10
14
even for output currents of several mA. The output cur-
rent capability of the circuit is limited only by power dissipation
in the source transistor.

Synchronization.
Since AD204s operate from a common
clock, synchronization is inherent. AD202s will normally not in-
teract to produce beat frequencies even when mounted on 0.25-
inch centers. Interaction may occur in rare situations where a
large number of long, unshielded input cables are bundled to-
gether and channel gains are high. In such cases, shielded cable
may be required or AD204s can be used.
APPLICATIONS EXAMPLES
Low-Level Sensor Inputs.
In applications where the output
of low-level sensors such as thermocouples must be isolated, a
low drift input amplifier can be used with an AD204, as shown
in Figure 17. A three-pole active filter is included in the design
to get normal-mode rejection of frequencies above a few Hz and
to provide enhanced common-mode rejection at 60 Hz. If offset
adjustment is needed, it is best done at the trim pins of the
OP07 itself; gain adjustment can be done at the feedback
resistor.

Note that the isolated supply current is large enough to mandate
the use of 1
μ
F supply bypass capacitors. This circuit can be
used with an AD202 if
a low-power op amp is used instead of
the OP07.
