Sales Briefcase
  • The UA741 is a high performance monolithic operational amplifier constructed on a single silicon chip. It is intended for a wide range of analog applications.

    The high gain and wide range of operating voltages provide superior performances in integrators, summing amplifiers and general feedback applications. The internal compensation network (6 dB/octave) ensures stability in closed-loop circuits.

    Key Features

    • Large input voltage range
    • No latch-up
    • High gain
    • Short-circuit protection
    • No frequency compensation required
    • Same pin configuration as the UA709
