1 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 25 mA by series protection resistors.
Note, however, that this degrades the low noise performance of the device.
Stresses at or above those listed under Absolute Maximum
Ratings may cause permanent damage to the product. This is a
stress rating only; functional operation of the product at these
or any other conditions above those indicated in the operational
section of this specification is not implied. Operation beyond
the maximum operating conditions for extended periods may
affect product reliability.

THERMAL RESISTANCE
θJA is specified for the device soldered on a 4-layer JEDEC
standard printed circuit board (PCB) with zero airflow for the
SOIC package, and a 2-layer JEDEC standard printed circuit
board (PCB) with zero airflow for the PDIP package.
