New Japan Radio Co.,Ltd. www.njr.com NJM4558/4559 DUAL OPERATIONAL AMPLIFIER GENERAL DESCRIPTION PACKAGE OUTLINE The NJM4558/4559 integrated circuit is a dual high-gain operational amplifier internally compensated and constructed on a single silicon chip using an advanced epitaxial process. Combining the features of the NJM741 with the close parameter matching and tracking of a dual device on a monolithic chip results NJM4558D NJM4558M in unique performance characteristics. Excellent channel NJM4559D NJM4559M separation allows the use of the dual device in single NJM741 ( DIP8 ) ( DMP8 ) operational amplifier applications providing density. It is especially well suited for applications in differential-in, differential-out as well as in potentiometric amplifiers and where gain and phase matched channels are mandatory.
