BIPOLAR ANALOG INTEGRATED CIRCUIT
µ
PC4093
J-FET INPUT LOW-OFFSET OPERATIONAL AMPLIFIER
The
µ
PC4093 operational amplifier is a high-speed version of the
µ
PC4091. 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
PC4093 is ideal for fast integrators, active filters, and other high-speed circuit applications.
FEATURES
• Stable operation with 220 pF capacitive load
• Low input offset voltage and offset voltage null
capability

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

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