6.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
VS Supply voltage, (V+) – (V–) Dual supply ±20 V
Single supply 40
Signal input pins(2) Voltage (V–) – 0.5 (V+) + 0.5 V
Current ±10 mA
ISC Output short-circuit(3) Continuous Continuous
TA Operating temperature –55 150 °C
TJ Junction temperature 150 °C
TSTG Storage temperature –65 150 °C
(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 pins are diode-clamped to the power-supply rails. Input signals that can swing more than 0.5 V beyond the supply rails must be current limited to 10 mA or less.
(3) Short-circuit to VS / 2 (ground in symmetrical dual-supply setups), one amplifier per package.
