5.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
Supply voltage VS = (V+) – (V–) Single-supply 6 V
Dual-supply ±3
Signal input pins Voltage Common-mode (V–) – 0.5 (V+) + 0.5 V
Differential (V+) – (V–) + 0.2
Current(3) ±10 mA
Output short circuit(2) Continuous Continuous
Temperature Operating, TA –55 150 °C
Junction, TJ 150
Storage, Tstg –65 150
(1) Stresses beyond those listed under Absolute Maximum Ratings can 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 can affect device reliability.
(2) Short-circuit to ground, one amplifier per package.
(3) Currents on input signal pins exceeding absolute maximum rating may increase the risk of latch-up. External current-limiting protection is required.
