Data Sheet

ADuM1300/ADuM1301

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 19

or Figure 20 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 ADuM1300/

ADuM1301.

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 the 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 19 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

RATED PEAK VOLTAGE

The insulation lifetime of the ADuM1300/ADuM1301 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 18, Figure 19, and Figure 20 illustrate these different

isolation voltage waveforms, respectively.

RATED PEAK VOLTAGE

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.
