Data Sheet

ADuM1400/ADuM1401/ADuM1402

In the case of unipolar ac or dc voltage, the stress on the

insulation is significantly lower, which allows operation at

higher working voltages while still achieving a 50-year service

life. The working voltages listed in Table 14 can be applied while

maintaining 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 22

or Figure 23 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 14.

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 ADuM140x.

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 14 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 a 50-year service life voltage. Operation at these high working

voltages can lead to shortened insulation life in some cases.

Note that the voltage presented in Figure 22 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.

RATED PEAK VOLTAGE

Figure 21. Bipolar AC Waveform

The insulation lifetime of the ADuM140x depends on the

voltage waveform type imposed across the isolation barrier.

The iCoupler insulation structure degrades at different rates

depending on whether the waveform is bipolar ac, unipolar

ac, or dc. Figure 21, Figure 22, and Figure 23 illustrate these

different isolation voltage waveforms, respectively.

RATED PEAK VOLTAGE

Figure 22. Unipolar AC Waveform

Bipolar ac voltage is the most stringent environment. The goal

of a 50-year operating lifetime under the ac bipolar condition

determines the Analog Devices recommended maximum

working voltage.
