THERMAL RESISTANCE
Storage Temperature Range −65°C to +125°C (N, R Suffix) θJA is specified for the device soldered on a 4-layer JEDEC Operating Temperature Range −40°C to +85°C standard printed circuit board (PCB) with zero airflow for the Lead Temperature (Soldering 60 sec) 300°C SOIC package, and a 2-layer JEDEC standard printed circuit board (PCB) with zero airflow for the PDIP package. 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.
