insulation structure degrades at different rates depending on
whether the waveform is bipolar ac, unipolar ac, or dc. Figure 8,
Figure 9, and Figure 10 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
determines the Analog Devices recommended maximum
working voltage.
In the case of unipolar ac or dc voltage, the stress on the insula-
tion is significantly lower. This allows operation at higher working
voltages and still achieves a 50-year service life. The working
voltages listed in Table 8 can be applied while maintaining the
50-year minimum lifetime, provided that the voltage conforms to
either the unipolar ac or dc voltage cases. Treat any cross
insulation voltage waveform that does not conform to Figure 9 or
Figure 10 as a bipolar ac waveform and limit its peak voltage to the
50-year lifetime voltage value listed in Table 8.
Note that the voltage presented in Figure 9 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.
