UA741 GENERAL PURPOSE SINGLE OPERATIONAL AMPLIFIERS LARGE INPUT VOLTAGE RANGE NO LATCH-UP HIGH GAIN SHORT-CIRCUIT PROTECTION NO FREQUENCY COMPENSATION REQUIRED 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.
