Description
The NJM324C / NJM324CA consist of four independent, high gain, internally frequency-compensated operational 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.

1. Input voltage is the voltage should be allowed to apply to the input terminal independent of the magnitude of VCC+
2. This input current only exists when the voltage at any of the input leads is driven negative. It is due to the collector-vase junction of the input PNP transistor
becoming forward-biased and thereby acting as input diode clamp. In addition to this diode action, there is 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 during
which an input is driven negative.
3. The junction base/substrate of the input PNP transistor polarized in reverse must be protected by a resistor in series with the inputs to limit the input current
to 400uA max (R= (Vin-32V)/400uA).
4. Short-circuit can cause excessive heating and destructive dissipation. Values are typical.
