µA741 (GENERAL PURPOSE OPERATION AMPLIFIER)

DESCRIPTION

The 741 is a general purpose monolithic operational amplifier. High Common mode, voltage, range and absence of 'Tatch-up" make the 741 ideal for use as a voltage follower. The high gain and wide range of operating voltage provides superior performance in integrator, summing amplifier and general feedback applications. The 741 is short-circuit protected and requires no external components for frequency compensation. The internal 6dB/octave roll-off insures stability in closed loop applications.


FEATURES

  • Internal frequency compensation
  • Short-circuit protection
  • Excellent temperature stability
