2 The AD797 inputs are protected by back-to-back diodes. To achieve low
noise, internal current-limiting resistors are not incorporated into the design
of this amplifier. If the differential input voltage exceeds ±0.7 V, the input
current should be limited to less than 2± mA by series protection resistors.
Note, however, that this degrades the low noise performance of the device.
