__High-Voltage S urge S uppression
These devices are not high-voltage arresters, nor are they
substitutes for surge suppressers. In systems that use
these forms of protection, however, the MAX366/MAX367
can fill a vital gap. Figure 7 shows a typical circuit.
Although the surge suppressers are extremely fast shunt
elements, they have very soft current knees. Their clamp
voltage must be chosen well above the normal signal
levels, because they have excessive leakage currents as
the knee is approached. This current can interfere with
normal operation when signal levels are low or imped-
ances are high. If the clamp voltage is too high, however,
the input can be damaged.
Using a MAX366/MAX367 after the surge suppresser
allows the surge-suppresser voltage to be set above
the supply voltage (but within the overvoltage limits),
dramatically reducing the effects of leakage (Figure 7).
During a surge, the surge suppresser clamps the input
voltage to roughly ±10V. This protects the
MAX366/MAX367, but the MAX366/MAX367 still dis-
connect the signal from the op amp well within the ±5V
supply.
