DESCRIPTION
The UA741 is a high performance monolithic oper-
ational amplifier constructed on a single silicon
chip. It is intented for a wide range of analog appli-
cations.

Function generator
The high gain and wide range of operating voltag-
es provide superior performances in integrator,
summing amplifier and general feedback applica-
tions. The internal compensation network (6dB/
octave) insures stability in closed loop circuits.
