permanent damage to the device. This is a stress rating only, and functional

operation of the device at these or any other conditions above those indicated in the

operational section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect device reliability.

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

will degrade the low noise performance of the device.

ESD SUSCEPTIBILITY

ESD (electrostatic discharge) sensitive device. Electrostatic

charges as high as 4000 volts, which readily accumulate on the

human body and on test equipment, can discharge without

detection. Although the AD797 features proprietary ESD pro-

tection circuitry, permanent damage may still occur on these

devices if they are subjected to high energy electrostatic dis-

charges. Therefore, proper ESD precautions are recommended

to avoid any performance degradation or loss of functionality.
