Absolute maximum ratings over operating free-air temperature range
Parameter Rating Unit
Supply voltage, VCC *1 32 V
Differential input voltage, VID *2 ±32 V
Input voltage, VI (either input) -0.3 to 32 V
Duration of output short circuit (one amplifier) to ground at
(or below) TA = 25,VCC 15 V *3 Unlimited
Package thermal impedance, θJA*4 76 /W
Operating virtual junction temperature, TJ150
Storage temperature range, Tstg -65 to 150
Charged-Device Model ±2kV
*1 All voltage values (except differential voltages and VCC specified for the measurement
of IOS) are with respect to the network GND.
*2 Differential voltages are at IN+, with respect to IN-.
*3 Short circuits from outputs to VCC can cause excessive heating and eventual destruction.
*4 Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable
power dissipation at any allowable ambient temperature is PD = (TJ(max)-TA)/θJA.
Operating at the absolute maximum TJ of 150 can affect reliability.
