BD3430 DAC Chip - MUS-ICT™ Series

ROHM's BD3430 DAC chip was developed as a part of the high-grade MUS-ICT series representing audio ICs. This series emphasizes spatial reverberation, quietness, and dynamic range, all qualities important for reproducing classical music. The original sound quality design technology makes it possible to successfully reproduce the target sound quality by incorporating a circuit in the signal processing block to check for audio quality. At the same time, low noise and distortion (130 dB SN ratio, -115 dB THD+N) provide the high performance demanded by high-fidelity audio equipment. Finally, the customizable digital filter, a key function of the digital signal processing circuit, supports the creation of the ideal sound sought by audio equipment manufacturers.

Designed to maximally extract and convert high-resolution audio data to analog, audio DAC chips are one of the most important components for determining the quality of audio equipment. Leveraging 50 years of expertise in developing audio ICs allowed ROHM to establish sound quality design technology capable of extracting the full amount of information from sound sources and offer products that deliver superior sound quality.
