High Quality Audio J-FET Input
Dual Operational Amplifier
■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE
The MUSES8920 is a high quality Audio J-FET input dual operational
amplifier. This is a mass production model of MUSES Series. By
inheriting MUSES Technology we pursued in the "MUSES series", the
MUSES8920 is compatible in high-quality sound and productivity. The
MUSES8920 has improved the chip layout and the material, and is
developing by thoroughly repeating the listening sound.
The characteristics Low noise (8nV/√Hz), high-SR (25V/µs) and low
distortion (0.00004%, Av=1) suitable for audio preamplifiers, active
filters, and line amplifiers. In addition, taking advantage of the low input
bias current that J-FET has, it is suitable for transimpedance amplifier
(I/V converter).
