High Quality Bipolar-Input Dual Audio Operational Amplifier
for High-end Audio
Equipment
MUSES8820
Data SheetWe 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.
