NOTES:

2. The inputs are protected by back-to-back diodes. Current-limiting resistors are not used in order to achieve low noise. Excessive

input current will flow if a differential input voltage in excess of approximately

±0.7 V is applied between the inputs unless some

limiting resistance is used.
