CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
1. This input current will only exist when the voltage at any of the input leads is driven negative. This current is due to the collector base junction of the
input p-n-p transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also lateral n-p-n
parasitictransistoractionontheICchip.ThistransistoractioncancausetheoutputvoltagesoftheamplifierstogototheV+voltagelevel(ortoground
for a large overdrive) for the time duration that an input is driven negative. This transistor action is not destructive and normal output states will re-
establish when the input voltage, which was negative, again returns to a value greater than -0.3V.
2. The maximum output current is approximately 40mA independent of the magnitude of V+. Continuous short circuits at V+ > 15V can cause
excessive power dissipation and eventual destruction. Short circuits from the output to V+ can cause overheating and eventual destruction of
the device.
