PC4741

HIGH PERFORMANCE QUAD OPERATIONAL AMPLIFIER

DESCRIPTION

The µPC4741 consists of four independent frequency compensated operational amplifiers featuring higher speed,
broader band than general purpose type as 741. The
such as active filters or pulse amplifiers.

FEATURES

• Internal frequency compensation

• Low noise

• Output short circuit protection

PC4741 is most appropriate for AC signal amplifier applications

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 –7.6 mW/°C when ambient temperature is higher than 50°C.

5. Thermal derating factor is –5.5 mW/°C when ambient temperature is higher than 25°C.
