Designed to extract and convert high-resolution digital audio data into analog audio signals at the highest level, audio DAC chips are one of the most important components in determining the quality of audio equipment.
Leveraging 50 years of experience in developing audio integrated circuits, ROHM has been able to define a "sound quality design technology" capable of extracting all the information from sound sources and thus delivering products that provide superior sound quality, including sound processors and power management integrated circuits.
Among them is the BD34301EKV, ROHM's flagship MUS-IC series DAC chip, which has received excellent evaluation results for its sound quality since its launch in February 2021.
Its adoption is steadily increasing worldwide. However, to meet the growing demand from manufacturers for a DAC chip that can be used in a wider range of audio equipment, ROHM has developed the BD34352EKV.
The new BD34352EKV DAC chip is specially designed to powerfully express the energy of sound sources while maintaining the natural, flat frequency response characteristic of ROHM's DAC chip design. It also incorporates an advanced digital filter, just like the BD34301EKV. This enables superior numerical performance (S/N ratio: 126 dB, THD+N: -112 dB) for the DAC chip, making it ideal for high-end audio equipment. Furthermore, the BD34352EKV is pin-compatible with the BD34301EKV and features the same customizable filter. This allows for different sound quality adjustments for each audio device, reducing development workload and contributing to the creation of the ideal sound sought by audio manufacturers.

ROHM's Contribution to Musical Culture:
For over 30 years, ROHM has been contributing to the popularization and development of musical cultures, focusing on classical music through the ROHM Music Foundation. This contribution includes academic scholarships for young musicians, through which we have supported 507 young musicians as of November 2021. The sponsored musicians, the "Rohm Music Friends," are currently active worldwide and, for example, are prize winners in international competitions and serve as principal players in orchestras.
We organize the Kyoto International Music Students Festival to promote international exchange among young musicians and the ROHM Music Seminar to support professional musicians. We also provide financial assistance for musical performances, research, and other disciplines. Furthermore, we host and collaborate on concerts and operas, supporting the ROHM Theatre Kyoto, a comprehensive theater company representing Japan.
