To provide protection for overvoltages up to 205 above

the supplies, a 1N±001 or 1N91± type diode should be

placed in series with the positive and negative supplies

as shown in Figure 2. The addition of these diodes will

reduce the analog signal range to 15 below the posi-

tive supply and 15 above the negative supply.

Protecting Against Fault

Conditions

Fault conditions occur when power supplies are turned

off when input signals are still present, or when over-

voltages occur at the inputs during normal operation. In

either case, source-to-body diodes can be forward

biased and conduct current from the signal source. If

this current is required to be kept to low (µA) levels

then the addition of eꢂternal protection diodes is rec-

ommended.
