MUSES8820D (NJR) - audio op amp (bipolar input)

Data Sheet

We have released the MUSES8820, mass production model of MUSES Series, offering finest sound to audio fans more widely. The MUSES8820 is a bipolar-input dual Operational Amplifier inheriting high quality sound development concept we pursued in the development of the MUSES01/02, and it employs chip-layout and lead-frame material optimized for mass production.
In addition to DIP package (lead insertion type), it employs halogen and lead-free surface mount package. The package provides mass productivity gain of audio equipment manufacturers and reduction of environmental impact. The MUSES8820 is most suitable for mass production models of high-end audio equipment reproducing the finest sound such as live sound of orchestra in the hall and breathing sound of player in live music house.
