NJM2068 Pinout, Equivalent and Applications

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.

Equivalent

Equivalent	Notes
NE5532	This IC has very similar performance and commonly using in audio pre amplifiers.
RC4558	This is older one with lower performance and suitable as a basic substitute
OPA2134	Using in higher end audio op amp devices with low noise and distortion
TL072	This is a JFET input op amp IC and its is not a direct substitute in all cases but popular
LM833	Has similar performance and used in low noise applications.
