Synchronization. Since AD204s operate from a common
clock, synchronization is inherent. AD202s will normally not
interact 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
together 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
REV. D

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 mF supply bypass capacitors. This circuit can be
used with an AD202 if a low power op amp is used instead of
the OP07.
Process Current Input with Offset. Figure 18 shows an
isolator receiver that 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.
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.
(NOTE: Circuit figures shown on this page are for SIP-style packages. Refer to
Page 3 for proper DIP package pinout.)
