(1) Refer to RETS124AX for LM124A military specifications and refer to RETS124X for LM124 military specifications.
(2) This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of
the input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is
also lateral NPN parasitic transistor action on the IC chip. This transistor action can cause the output voltages of the op amps to go to
the V
+
voltage level (or to ground for a large overdrive) for the time duration that an input is driven negative. This 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 (at 25°C).
(3) For operating at high temperatures, the LM324/LM324A/LM2902 must be derated based on a +125°C maximum junction temperature
and a thermal resistance of 88°C/W which applies for the device soldered in a printed circuit board, operating in a still air ambient. The
LM224/LM224A and LM124/LM124A can be derated based on a +150°C maximum junction temperature. The dissipation is the total of
all four amplifiers—use external resistors, where possible, to allow the amplifier to saturate of to reduce the power which is dissipated in
the integrated circuit.
(4) 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 +15V,
continuous short-circuits can exceed the power dissipation ratings and cause eventual destruction. Destructive dissipation can result
from simultaneous shorts on all amplifiers.
