PC4742
SINGLE SUPPLY VOLTAGE, HIGH SPEED,
WIDE BAND, DUAL OPERATIONAL AMPLIFIERS
The
µ
PC4742 is dual high speed, wide band operational amplifier designed for single supply operation from
+3 V to +32 V with low supply current drain. By using high speed PNP transistors for input and output circuits,
the excellent AC performance is achieved without degrading capacitive load drive capability.
With no crossover distortion and wide output voltage range characteristics, the
µ
PC4742 is optimum choice for
single supply AC amplifier, and active filters.
FEATURES
• High slew rate: 7 V/

• Wide supply voltage range: +3 V to +32 V
• Wide output voltage swing
• Common mode input voltage range includes V
–
• Internal frequency compensation
• Output short circuit protection

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 –5.0 mW/°C when operating ambient temperature is higher than 55
°C.
5.
Thermal derating factor is –4.4 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.
