DESCRIPTION
The UA741 is a high performance monolithic operational amplifier constructed on a single silicon chip.
It is intented for a wide range of analog applications.
Summing amplifier
Voltage follower
Integrator
Active filter
Function generator
The high gain and wide range of operating voltages
provide superior performances in integrator, summing amplifier and general feedback applications.
The internal compensationnetwork (6dB/octave)insures stability in closed loop circuits.
