The MC4741C is a true quad MC1741. Integrated on a single monolithic
chip are four independent, low power operational amplifiers which have been
designed to provide operating characteristics identical to those of the
industry standard MC1741, and can be applied with no change in circuit
performance.

The MC4741C can be used in applications where amplifier matching or
high packing density is important. Other applications include high
impedance buffer amplifiers and active filter amplifiers.

• Each Amplifier is Functionally Equivalent to the MC1741

• Class AB Output Stage Eliminates Crossover Distortion

• True Differential Inputs

• Internally Frequency Compensated

• Short Circuit Protection

• Low Power Supply Current (0.6 mA/Amplifier)
