ADuM3223/ADuM4223
INSULATION LIFETIME
All insulation structures eventually break down when subjected
to voltage stress over a sufficiently long period. The rate of insu-
lation 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 ADuM3223 /
ADuM4223 .
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 12 summarize the peak voltage for
50 years of service life for a bipolar ac operating condition, and
the maximum CSA/VDE approved working voltages. In many
cases, the approved working voltage is higher than 50-year
service life voltage. Operation at these high working voltages
Data Sheet
is significantly lower. This allows operation at higher working
voltages while still achieving a 50-year service life. Any cross-
insulation voltage waveform that does not conform to Figure 26
or Figure 27 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 12.
Note that the voltage presented in Figure 26 is shown as sinu-
soidal 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.

different isolation voltage waveforms.
A bipolar ac voltage environment is the worst case for the
i Coupler products and is the 50-year operating lifetime that
Analog Devices recommends for maximum working voltage. In
the case of unipolar ac or dc voltage, the stress on the insulation
