Note 1

Absolute Maximum Ratings indicate limits beyond which damage to the device may

occur. Operating Ratings indicate conditions for which the device is intended to be

functional, but specific performance is not guaranteed. For guaranteed specifications and

the test conditions, see the Electrical Characteristics.

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 T J(MAX) , θ JA , and Ta. The

maximum allowable power dissipation at any ambient temperature is P D = (T J(MAX) - Ta)/

θ JA . All numbers apply for packages soldered directly onto a PC board.

Note 4: Vo=1.4V, Rs = 0? 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 + .

Note 7: Due to proximity of external components, insure that coupling is not originating via

stray capacitance between these external parts. This typically can be detected as this type of

capacitance increases at higher frequencies.
