DESCRIPTION
The LM124/124A consists of four independent, high
gain, internally frequency compensated operational
amplifiers which were designed specifically to operate
from a single power supply over a wide range of
voltages. Operation from split power supplies is also
possible and the low power supply current drain is
independent of the magnitude of the power supply
voltage.
Application areas include transducer amplifiers, DC
gain blocks and all the conventional op amp circuits
which now can be more easily implemented in single
power supply systems. For example, the LM124/124A
can be directly operated off of the standard +5Vdc
power supply voltage which is used in digital systems
and will easily provide the required interface
electronics without requiring the additional +15Vdc
power supplies.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is functional, but do not ensure specific performance limits. For ensured specifications and test conditions, see the
Electrical Characteristics. The ensured specifications apply only for the test conditions listed. Some performance characteristics may
degrade when the device is not operated under the listed test conditions.
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
DC
(at
25°C).
The maximum power dissipation must be derated at elevated temperatures and is dictated by T
Jmax
(maximum junction temperature),
ThetaJ
A
(package junction to ambient thermal resistance), and T
A
(ambient temperature). The maximum allowable power dissipation at
any temperature is P
Dmax
= (T
Jmax
- T
A
)/ThetaJ
A
or the number given in the Absolute Maximum Ratings, whichever is lower.
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
DC
, continuous short-circuits can exceed the power dissipation ratings and cause eventual destruction. Destructive dissipation can
result from simultaneous shorts on all amplifiers.
