Figure 36. Basic Connections
BASIC CONNECTION
Figure 36 shows the basic connection circuit for the AD8223.
The +VS and VS terminals are connected to the power supply.
The supply can be either bipolar (VS = ±2 V to ±12 V) or single
supply (VS = 0 V, +VS = +3 V to +24 V). Power supplies should
be capacitively decoupled close to the power pins of the device.
For best results, use surface-mount 0.1 μF ceramic chip capacitors
and 10 μF electrolytic tantalum capacitors.
The input voltage, which can be either single-ended (tie either
IN or +IN to ground) or differential, is amplified by the
programmed gain. The output signal appears as the voltage
difference between the output pin and the externally applied
voltage on the REF input.
DIFFERENTIAL OUTPUT
Figure 37 shows how to create a differential output in-amp. An
OP1177 op amp creates the inverted output. Because the op
amp drives the AD8223 reference pin, the AD8223 can still
ensure that the differential voltage is correct. Errors from the
op amp or mismatched resistors are common to both outputs
and are thus common mode. These common-mode errors
should be rejected by the next device in the signal chain.

OUTPUT BUFFERING
The AD8223 is designed to drive loads of 10 kΩ or greater. If
the load is less than this value, buffer the AD8223 output with a
precision single-supply op amp such as the OP113. This op amp
can swing from 0 V to 4 V on its output while driving a load as
small as 600 Ω.

CABLES
Receiving from a Cable
In many applications, shielded cables are used to minimize
noise; for best CMR over frequency, the shield should be
properly driven. Figure 39 shows an active guard drive that
is configured to improve ac common-mode rejection by
bootstrapping the capacitances of input cable shields, thus
minimizing the capacitance mismatch between the inputs.
