Note 2:

Short circuits from the output to V+ can cause excessive heating and eventual destruction. When

considering short circuits to ground, the maximum output current is approximately 40mA

independent of the magnitude of V+. At values of supply voltage in excess of +15V, continuous

short-circuits can exceed the power dissipation ratings and cause eventual destruction. Destructive

dissipation can result from simultaneous shorts on all amplifiers.

Note 3:

The maximum power dissipation is a function of TJ(MAX) , θJA , and TA. The maximum allowable power

dissipation at any ambient temperature is PD = (TJ(MAX) - Ta)/ θJA. All numbers apply for packages

soldered directly onto a PC board.

Note 4:

Vo=1.4V, Rs = 0Ω with V+ from 5V to 30V; and over the full input common-mode range (0V to V+

-1.5V) at 25°C.

Note 5:

The direction of the input current is out of the IC due to the PNP input stage. This current is

essentially constant, independent of the state of the output so no loading change exists on the input

lines.

Note 6:

The input common-mode voltage of either input signal voltage should not be allowed to go negative

by more than 0.3V (at 25°C). The upper end of them common-mode voltage range is V+ -1.5V (at

25°C), but either or both inputs can go to +32V without damage, independent of the magnitude of V+.
