IJA741

FREQUENCY-COMPENSATED OPERATIONAL AMPLIFIER

FAIRCHILD LINEAR INTEGRATED CIRCUITS

GENERAL DESCRIPTION - The I'A741 is a high performance monolithic Operational Amplifier CONNECTION DIAGRAMS
constructed using the Fairchild Planar" epitaxial process. It is intended for a wide range of analog
applications. High common mode voltage range and absence of latch-up tendencies make the I'A741 8-PIN METAL CAN
ideal for use as a voltage follower. The high gain and wide range of operating voltage provides superior (TOP VIEW)
performance in integrator, summing amplifier, and general feedback applications. PACKAGE OUTLINE 58
