DUAL OPERATIONAL AMPLIFIE R
■ G ENE RA L DESCRIPTION ■ PACKAGE OUTLINE
The NJM4558 is a dual high-gain operational amplifier with
internal compensation circuit and constructed on a single silicon
chip. It offers excellent characteristics by combining the
parameters adjusted for a monolithic chip. The channel separation
characteristic is suitable for measuring instruments.
