ROHM leverages its more than 50 years of experience in developing audio integrated circuits to establish superior sound quality design technology, offering products such as high-fidelity sound processors and high-quality audio power integrated circuits.

ROHM's latest product is based on the first-generation MUS-IC™ BD34301EKV audio DAC chip, renowned for its sound quality and widely adopted in high-end models from various companies. The BD34302EKV inherits ROHM's core DAC chip design concept—natural, flat sound—and adds the three elements of spatial reverb, silence, and dynamic range from the MUS-IC™ series to authentically reproduce the "texture" of musical instruments and achieve an even more realistic audio experience.

By incorporating a new Data Weighted Average (DWA) algorithm, the BD34302EKV achieves a THD+N characteristic of -117dB (THD: -127dB), a key performance indicator that enhances sound quality by delivering a realistic sense of texture. Simultaneously, the 130dB signal-to-noise ratio (SNR) provides acoustic performance worthy of a flagship DAC chip, while a sampling rate of up to 1,536kHz allows customers to fully utilize the high-precision calculations of their digital signal processors (DSPs).

In monaural mode, which assigns one DAC chip per channel, ROHM's patented HD (High Definition) monaural mode contributes to a smoother, more natural sound. As part of the MUS-IC™ series, uncompromising craftsmanship has been applied to even the smallest details. Drawing on years of experience in sound-quality design, the optimal bonding cable material was selected for each terminal of the BD34302EKV to accurately convey the natural "texture" of musical instruments. These features help create the ideal sound sought after by high-end audio manufacturers.
