The NJM2068 is a high performance, low noise and dual op-amp designed for audio and precision applications. The IC offers improved noise performance, distortion, slew rate and gain bandwidth over traditional op-amps like the 4558 IC. In this article I’m sharing the information’s about NJM2068 Pinout, Equivalent and Applications.
