APPLICATION NOTES
COMMON-MODE TRANSIENT IMMUNITY
In general, common-mode transients consist of linear and
sinusoidal components. The linear component of a common-
mode transient is given by
where ΔV/Δt is the slope of the transient shown in Figure 11
and Figure 12.
The transient of the linear component is given by
Figure 8 characterizes the ability of the ADuM1234 to operate
correctly in the presence of linear transients. The data is based
on design simulation and is the maximum linear transient
magnitude that the ADuM1234 can tolerate without an
operational error. This data shows a higher level of robustness
than what is listed in Table 5 because the transient immunity
values obtained in Table 5 use measured data and apply
allowances for measurement error and margin.
The sinusoidal component (at a given frequency) is given by
where:
V
f is the frequency of the sinusoidal.
The transient magnitude of the sinusoidal component is given by
Figure 9 and Figure 10 characterize the ability of the
ADuM1234 to operate correctly in the presence of sinusoidal
transients. The data is based on design simulation and is the
maximum sinusoidal transient magnitude (2πf V
ADuM1234 can tolerate without an operational error. Values
for immunity against sinusoidal transients are not included in
Table 5 because measurements to obtain such values have not
been possible.
