DESCRIPTION
The MC145 8 is high performanc e monolithic dual
operational am plifier intended for a w ide range of
analog applications:
❑Summing amplifier
❑Voltage follower
❑Integrator
❑Active filter
❑Function gen erator
The high gain and wide range of operating voltag-
es provide superior performance in integrator,
summing amplifiers and general feedback appli-
catons.
