Notes :
1. Shor t -cir cui t s f rom t he out put t o VCC can cause excessi ve heat i ng if VC C > 15V. T he maxi mum out put cur rent
is approximately 40mA independent of the magnitude of VC C. Destructive di ssipation can res ult from simul ta-
neous short-circuit on all amplifiers.
2. The di r ect ion of the i nput cur rent is out of t he IC . Thi s cur r ent is essenti al l y constant, i ndependent of the st ate
of the output so no loading change exists on the input lines.

5. Due t o the proxi mit y of ex ternal component s insure t hat coupl ing i s not ori gi nat ing vi a str ay capaci t ance be-
tween these external parts. This typically can be detected as this type of capacitance increases at higher fre-
quences.
6. This input cur rent onl y exi sts w hen t he volt age at any of t he i nput leads is dr iven negat ive. It i s due t o t he
collector-base junction of the input PNP transistor becoming forward biased and thereby acting as input di-
odes clamps. In addition to thi s diode action, there is also NPN parasitic action on the IC chip. this transistor
action can cause the output voltages of the Op-amps to go to the VCC voltage level (or to ground for a large
overdrive) for the time duration than an input is driven negative.
This is not destructive and normal output will set up again for input voltage higher than -0.3V.
