These specifications are limited to

−55°C ≤ TA ≤ +125°C for the LM124-N/LM124A. With the LM224-N/LM224A, all temperature

specifications are limited to

−25°C ≤ TA ≤ +85°C, the LM324-N/LM324A temperature specifications are limited to 0°C ≤ TA ≤ +70°C, and

the LM2902-N specifications are limited to

−40°C ≤ TA ≤ +85°C.

(2)

VO ≃ 1.4V, RS = 0 Ω with V

+ from 5 V to 30 V; and over the full input common-mode range (0 V to V+ − 1.5 V) for LM2902-N, V+ from 5

V to 26 V.

(3)

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.

(4)

The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3 V (at 25°C). The

upper end of the common-mode voltage range is V+

− 1.5 V (at 25°C), but either or both inputs can go to 32 V without damage (26 V for

LM2902-N), independent of the magnitude of V+.

(5)

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.

(6)

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

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

from simultaneous shorts on all amplifiers.
