6.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted)(1)
MINMAXUNIT
VS Supply voltage 40 V
VIN Input voltage(2) (V–) – 0.5 (V+) + 0.5 V
IIN Input current(2) ±10 mA
VIN(DIFF) Differential input voltage ±VS V
IO Output short-circuit(3) Continuous
TA Operating temperature –55 125 °C
TJ Junction temperature –65 150 °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. The input voltage and output negative-voltage ratings can be exceeded if the input and output current ratings are followed.
(3) Short-circuit to VS / 2 (ground in symmetrical dual-supply setups), one amplifier per package.
