SAME PIN CONFIGURATION AS THE UA709
ESD INTERNAL PROTECTION
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 operatingvoltages
provide superior performances in integrator, summing amplifier and general feedback applications.
The internal compensation network (6dB / octave)
insures stability in closed loop circuits.
