DESCRIPTION
These circuits consist of four independent, high
gain, internally frequency compensated operation-
al amplifiers. They 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.
All the pins are protected against electrostatic dis-
charges up to 2000V (as a consequence, the input
voltages must not exceed the magnitude of VCC+
or VCC-.)

SCHEMATIC DIAGRAM (1/4 LM124W)
ABSOLUTE MAXIMUM RATINGS Either or both input voltages must not exceed the magnitude of VCC+ or VCC-. Short-circuits from the output to VCC can cause excessive heating if VCC > 15V. The maximum output current is approximately 40mA independent of the magnitude of VCC. Destructive dissipation can result from simultaneous short-circuit on all amplifiers. This input current only exists when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP transistor becoming forward biased and thereby acting as input diodes clamps. In addition to this diode action, there is also NPN parasitic action on
the IC chip. this transistor action can cause the output voltages of the Op-amps to go to the VCC voltage level (or to ground for a large overdrive) for the time duration than an input is driven negative. This is not destructive and normal output will set up again for input voltage higher than -0.3V.

4/13 The direction of the input current is out of the IC. This current is essentially constant, independent of the state of the output so no loading change
exists on the input lines. Vo = 1.4V, Rs = 0Ω, 5V < VCC+ < 30V, 0 < Vic < VCC+ - 1.5V The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the
common-mode voltage range is VCC+ - 1.5V, but either or both inputs can go to +32V without damage. Due to the 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 frequences.
