this current is required to be kept to low (µA) levels  
then the addition of external protection diodes is rec-  
ommended.

To provide protection for overvoltages up to 20V above  
the supplies, a 1N4001 or 1N914 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 1V below the posi-  
tive supply and 1V above the negative supply.
