6.1 Absolute Maximum Ratings

over operating ambient temperature range (unless otherwise noted) (1)
MIN MAX UNIT
Supply voltage, VS = (V+) – (V–) 0 42 V
Signal input pins Common-mode voltage (3) (V–) – 0.5 (V+) + 0.5 V
Differential voltage (3) VS + 0.2 V
Current (3) –10 10 mA
Output short-circuit (2) Continuous
Operating ambient temperature, TA –55 150 °C
Junction temperature, TJ 150 °C
Storage temperature, Tstg –65 150 °C
(1) Operating the device beyond the ratings listed under Absolute Maximum Ratings will cause permanent damage to the device. These are stress ratings only, based on process and design limitations, and this device has not been designed to function outside the conditions indicated under Recommended Operating Conditions. Exposure to any condition outside Recommended Operating Conditions for extended periods, including absolute-maximum-rated conditions, may affect device reliability and performance.
(2) Short-circuit to ground, one amplifier per package. This device has been designed to limit electrical damage due to excessive output current, but extended short-circuit current, especially with higher supply voltage, can cause excessive heating and eventual thermal destruction. See the Thermal Protection section for more information.
(3) Input pins are diode-clamped to the power-supply rails. Input signals that may swing more than 0.5 V beyond the supply rails must be current limited to 10 mA or less.
