The Sound of Perfection: How Nisshinbo’s MUSES8921 Brings Emotion Back to Audio

In the world of audio, precision often takes center stage. Engineers chase numbers, specifications, and measurements, striving to minimize noise and distortion. Yet, for Nisshinbo Micro Devices, true innovation lies somewhere else: in emotion.

The MUSES8921 isn’t just an operational amplifier. It’s a statement, that sound should move us.

Committed to bringing exceptional audio technologies to engineers and creators, we believe the MUSES8921 embodies the perfect harmony between science and soul.

The MUSES name has long been synonymous with pure, natural sound. Since its inception, the series has represented Nisshinbo’s relentless pursuit of audio perfection. Each generation has built upon decades of analog expertise, with engineers refining every circuit to bring music to life just as the artist intended.

With the MUSES8921, that pursuit continues, now powered by a J-FET input architecture and an obsessive attention to the smallest sonic details.

It’s not just evolution. It’s the culmination of over 50 years of craftsmanship and curiosity in sound design.

Beneath its artistry lies remarkable engineering. The MUSES8921 offers specifications that make it a natural choice for high-fidelity and professional audio applications:

• Input Noise Voltage: 8.0 nV/√Hz typ
• Gain Bandwidth Product: 11.0 MHz typ
• Total Harmonic Distortion: 0.0004% typ
• High Slew Rate: 25 V/μs typ
• Low Input Bias Current: 5 pA typ

These characteristics make it ideal for applications such as preamplifiers, I/V converters, headphone amps, and studio reference systems, wherever accuracy and emotion must coexist.

Housed in a compact DFN4035-8-GR package, the MUSES8921 delivers both design flexibility and outstanding heat dissipation.

This means engineers can build smaller, more efficient, and more reliable systems without compromising sonic integrity, a critical advantage in today’s space-constrained audio designs.

As an official partner of Nisshinbo Micro Devices, we are proud to bring products like the MUSES8921 to our customers, innovators, audio designers, and engineers who share the same belief: That sound should be felt, not just heard.

Whether it’s powering a desktop DAC, enhancing a car audio system, or fine-tuning a professional studio, the MUSES8921 offers a foundation for uncompromising sound reproduction.

The MUSES8921 is more than just an addition to the MUSES family, it’s an invitation to rediscover what pure soundreally means.

At Macnica ATD Europe, we are read to support engineers and designers bring that vision to life, connecting technology and emotion through the art of sound.
