DUAL GENERAL PURPOSE OPERATIONAL AMPLIFIER
■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE
The NJM1458 is a monolithic pair of Internally Compensated
High Performance Amplifiers, constructed using the New JRC
Planar epitaxial process. They are intended for a wide range of
analog applications where board space or weight is important.
High common mode voltage range and absence of “latch-up”
make the NJM1458 ideal for use as voltage followers. The high
gain and wide range of operating voltage provides superior
performance in integrator, summing amplifier and general
feedback applications.
The NJM1458 is short-circuit protected and require no
external components for frequency compensation. The internal
6 dB/octave roll-off insures stability in closed loop applications.
For single amplifier performance, see the NJM741 data sheet.
