BIPOLAR ANALOG INTEGRATED CIRCUIT
PC324
LOW POWER QUAD OPERATIONAL AMPLIFIER
DESCRIPTION
The
PC324 is a quad operational amplifier which is
designed to operate from a single power supply over a
wide range of voltages. Operation from split power
supplies is also possible and the power supply current
drain is very low. Further advantage, the input common-
mode voltage can also swing to ground in the linear
mode.

Notes 1. Reverse connection of supply voltage can cause destruction.
2. The input voltage should be allowed to input without damage or destruction independent of the
magnitude of V
+
. Either input signal should not be allowed to go negative by more than 0.3 V. The normal
operation will establish when the both inputs are within the Common Mode Input Voltage Range of
electrical characteristics.
3. This specification is the voltage which should be allowed to supply to the output terminal from external
without damage or destructive. Even during the transition period of supply voltage, power on/off etc.,
this specification should be kept. The output voltage of normal operation will be the Output Voltage Swing
of electrical characteristics.
4. Thermal derating factor is 7.6 mW/
C when operating ambient temperature is higher than 50
C.
5. Thermal derating factor is 5.5 mW/
C when operating ambient temperature is higher than 25
C.
6. Pay careful attention to the total power dissipation not to exceed the absolute maximum ratings, Note
4 and Note 5.
