PC4094
J-FET INPUT LOW-OFFSET DUAL OPERATIONAL AMPLIFIER
Dual operational amplifier
µ
PC4094 is a high-speed version of the
µ
PC4092. NEC's unique high-speed PNP transistor (f
T
= 300 MHz) in the output stage realizes a high slew rate of 25 V/
µ
s under voltage-follower conditions without an oscillation
problem. Zener-zap resistor trimming in the input stage produces excellent offset voltage and temperature drift
characteristics.
With AC performance characteristics that are two times better than conventional bi-FET operation amplifiers, the
µ
PC4094 is ideal for fast integrators, active filters, and other high-speed circuit applications.

Notes 1.
Reverse connection of supply voltage can cause destruction.
2.
The input voltage should be allowed to input without damage or destruction. Even during the transition period
of supply voltage, power on/off etc., this specification should be kept. 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.

Note
Input bias currents flow into IC. Because each currents are gate leak current of P-channel J-FET on input stage.
And that is temperature sensitive. Short time measuring method is recommendable to maintain the junction
temperature close to the operating ambient temperature.
