AD8556
Rev. A | Page 25 of 28
To show the benefits that the AD8556 brings to new applications
where EMI/RFI signals are present, a part was programmed
with a gain of 70 and a dc offset of 2.5 V to produce a VOUT of
0 V. A test circuit like that shown in Figure 52 was used.
Figure 52 simulates the presence of a noisy common-mode
signal, and Figure 53 shows the response dc values at VOUT.

Figure 53. DC Offset Values at VOUT Caused by Frequency Seep of Input
The differential bandwidth defines the frequency response of
the filters with a differential signal applied between the two
inputs, VPOS (that is, +IN ) and VNEG (that is, –IN). Figure 54
shows the circuit used to test for AD8556 EMI/RFI susceptibility.
The part is programmed as previously stated during the
common-mode testing.

Figure 55. Response of AD8556 to EMI/RFI Differential Signals
To make a board robust against EMI, the leads at VPOS and
VNEG should be as similar as possible. In this way, any EMI
received by the VPOS and VNEG pins will be similar (that is, a
common-mode input), and rejected by the AD8556. Furthermore,
additional filtering at the VPOS and VNEG pins should give a
better reduction of unwanted behavior compared with filtering
at the other pins.
