(1)
Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress
ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under
Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device
reliability.
(2)
Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.5V beyond the supply rails
should be current-limited to 10mA or less.
(3)
Short-circuit to ground, one amplifier per package.
5.2 ESD Ratings

(1)
JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2)
JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
