Nisshinbo Micro Devices has launched the MUSES8921, a J-FET input, dual operational amplifier designed specifically for high-quality audio applications.
This new device is aimed at home, professional, portable, and car audio systems, serving as the next-generation J-FET model in the MUSES series. It focuses on reproducing the original sound signal with remarkable clarity, ambience, and dynamic precision.
Key Features and Specifications
Ultra-Low Noise: 8.0 nV/√Hz at 1 kHz — delivering crystal-clear sound with minimal interference.
Low Distortion: Total harmonic distortion (THD) of 0.0004% at 1 kHz ensures transparent signal amplification.
High Slew Rate: 25 V/µs, enabling accurate handling of fast, dynamic audio signals.
Wide Operating Voltage Range: ±3.5 V to ±17 V — suitable for diverse audio circuit designs.
Package Options: Available in EMP-8-AN and DFN4035-8-GR packages for compact and portable applications.
Applications
- High-end home audio systems
- Professional sound equipment
- Portable and car audio amplifiers
- Aftermarket sound upgrades
Building on the success of the MUSES8920/A, the new MUSES8921 refines its predecessor’s performance, setting a new benchmark for audiophile-grade J-FET op-amps.
