IC 741 Details

The IC 741 is a high performance monolithic operational amplifier constructed using the instrumentation process.  High common mode voltage range and absence of latch-up tendencies make the IC 741 ideal for use as voltage follower.  The high gain and wide range of operating voltage provide superior performance in integrator, summing amplifier and general feed back applications.
