ADuM1200/ADuM1201

Data Sheet

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

lation is significantly lower, which allows operation at higher

working voltages yet still achieves a 50-year service life. The

working voltages listed in Table 14 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 16

or Figure 17 is to be treated as a bipolar ac waveform, and its

peak voltage is to 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 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 ADuM120x.

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 volt-

ages. 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 16 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.

RATED PEAK VOLTAGE

Figure 15. Bipolar AC Waveform

The insulation lifetime of the ADuM120x 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 15, Figure 16, and Figure 17 illustrate these

different isolation voltage waveforms, respectively.

RATED PEAK VOLTAGE

Figure 16. 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.
