MUS-IC™ Series, 32-bit, 1536 kHz Sampling Stereo Audio D/A Converter
BD34302EKV is a D/A converter for high-quality audio that incorporates ROHM's unique sound quality design technology. The newly developed DWA improves THD performance and provides higher resolution and more natural sound quality with HD (High Definition) monaural mode. In addition, an automatic mode switching function makes it possible to easily switch between PCM/DSD and between different sampling frequencies.
It is the masterpiece of ROHM audio IC which pursues both the numerical values and sound quality performance required in an audio device to the utmost limits and created through the ardency of ROHM engineeers. That is ROHM Musical Device "MUS-IC".
