Overvoltage Protection
If sustained operation with no supplies but with analog
signals applied is possible, it is recommended that diodes
(such as 1N914) be inserted in series with the supply lines to
the IH5352. Such conditions can occur if these signals come
from a separate power supply or another location, for
example. The diodes will be reverse biased under this type
of operation, preventing heavy currents from flowing from the
analog source through the IH5352.
The same method of protection will provide over
±
25V
overvoltage protection on the analog inputs when the
supplies are present. The schematic for this connection is
shown in Figure 8.
