6.1 Absolute Maximum Ratings

Over operating free-air temperature range, unless otherwise noted.(1)
MIN MAX UNIT
Supply voltage 7 V
Signal input terminals Voltage(2) (V–) – 0.5 (V+) + 0.5 V
Current(2) –10 10 mA
Output short-circuit(3) Continuous mA
Operating temperature, TA –40 150 °C
Junction temperature, TJ °C
Storage temperature, Tstg –65 150 °C
(1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not supported.
(2) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.5 V beyond the supply rails should be current limited to 10 mA or less.
(3) Short-circuit to ground, one amplifier per package.

6.2 ESD Ratings
