Data Sheet
INSULATION LIFETIME
All insulation structures eventually break down when subjected
to voltage stress over a sufficiently long period. The rate of
insulation degradation is dependent on the characteristics of the
voltage waveform applied across the insulation. In addition to
the testing performed by the regulatory agencies, Analog
Devices carries out an extensive set of evaluations to determine
the lifetime of the insulation structure within the ADuM221x.
Analog Devices performs accelerated life testing using voltage
levels higher than the rated continuous working voltage. Accel-
eration factors for several operating conditions are determined.
These factors allow calculation of the time to failure at the actual
working voltage. The values shown in Table 19 summarize the
peak voltage for 50 years of service life for a bipolar ac operating
condition and the maximum CSA/VDE approved working volt-
ages. In many cases, the approved working voltage is higher than
a 50-year service life voltage. Operation at these high working
voltages can lead to shortened insulation life in some cases.
The insulation lifetime of the ADuM221x depends on the voltage
waveform type imposed across the isolation barrier. The i Coupler
insulation structure degrades at different rates, depending on
whether the waveform is bipolar ac, unipolar ac, or dc. Figure 16,
Figure 17, and Figure 18 illustrate these different isolation
voltage waveforms.
Bipolar ac voltage is the most stringent environment. The goal
of a 50-year operating lifetime under the ac bipolar condition
ADuM2210/ADuM2211
working voltages while still achieving a 50-year service life. The
working voltages listed in Table 19 can be applied while main-
taining the 50-year minimum lifetime, provided the voltage
conforms to either the unipolar ac or dc voltage cases. Any
cross-insulation voltage waveform that does not conform to
Figure 17 or Figure 18 should be treated as a bipolar ac
waveform and its peak voltage should be limited to the 50-year
lifetime voltage value listed in Table 19.
Note that the voltage presented in Figure 17 is shown as
sinusoidal for illustration purposes only. It is meant to represent
any voltage waveform varying between 0 V and some limiting
value. The limiting value can be positive or negative, but the
voltage cannot cross 0 V.

In the case of unipolar ac or dc voltage, the stress on the
insulation is significantly lower. This allows operation at higher
