NJM4558L dual op amp from JRC in a SIP8 package. The NJM4558L is the same as the DIP NJM4558 (JRC4558) otherwise. The SIP version is a great replacement for dual op amps in vintage circuits as well as a space saving package for some PCB layouts.

The NJM4558L 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.
