ROHM’s 2nd Generation MUS-IC Series Audio DAC Chip for Hi-Res Audio Playback with Exclusive HD Monaural Mode
Delivers an authentic listening experience by expressing the three elements of spatial reverberation, quietness, and dynamic range while preserving the natural “texture” of musical instruments
Santa Clara, CA and Kyoto, Japan, Jan. 22, 2025 (GLOBE NEWSWIRE) -- today announced a new 32-bit D/A converter IC (DAC chip) and evaluation board designed for flagship models in the MUS-IC™ series optimized for high-resolution audio playback.
Engineered to maximally extract and accurately convert high-resolution sound data to analog, DAC chips are crucial for determining audio equipment quality. ROHM leverages over 50 years of expertise in audio IC development to establish superior sound quality design technology, offering products such as high-fidelity sound processors and high-quality audio power ICs.
ROHM’s latest product builds on the 1st generation MUS-IC audio DAC chip, renowned for its sound quality and widely adopted in high-end models from various companies. The inherits the core design concept behind ROHM’s DAC chip – natural flat sound – and by adding the three elements of spatial reverberation, quietness, and dynamic range from the MUS-IC series to authentically reproduce the “texture” of musical instruments for an even more realistic audio experience.
By incorporating a new algorithm for Data Weighted Averaging (DWA), the achieves a THD+N characteristic of -117dB (THD: -127dB), a key performance indicator that enhances sound quality by achieving a sound quality that conveys a realistic sense of texture. At the same time, the signal-to-noise ratio (SNR) of 130dB provides noise performance befitting a flagship DAC chip, while a sampling frequency of up to 1,536kHz allows customers to fully leverage the high-precision calculations of their digital signal processors (DSPs).
In monaural mode, which allocates one DAC chip per channel, ROHM’s proprietary HD (High Definition) monaural mode contributes to smoother, more natural sound. As part of the MUS-IC series, uncompromising craftsmanship has been applied down to the smallest details. Based on years of expertise in sound quality design, the optimal bonding wire material for each terminal of the was selected to accurately convey the natural “texture” of musical instruments. These features help create the ideal sound sought by high-end audio manufacturers.
