Description
The NJM324C 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. Short-circuits from the output to VCC can cause excessive heating if VCC > 15V. Destructive dissipation can result from simultaneous short circuits on all
amplifiers.
3. 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.
4. 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).
5. Short-circuit can cause excessive heating and destructive dissipation. Values are typical.

1. VO = 1.4V, RS=0Ω, 5V < VCC < 30V, 0 < Vic < VCC - 1.5V.
2. The direction of the input current is out of the IC.
3. 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.
4. Due to the proximity of the external components, ensure that stray capacitance between these external parts dose not cause coupling. Coupling can be
detected because this type of capacitance increases at higher frequencies.
5. This parameter is not 100% test.
