32-bit D/A converter IC "BD34301EKV" for high-quality audio equipment

     ROHM, a world-renowned semiconductor manufacturer, has released a 32-bit D/A converter IC "BD34301EKV" for high-quality audio equipment that plays high-resolution sound sources*1 and its evaluation board "BD34301EKV-EVK-001"

     It is generally considered that the DAC chip of the audio equipment is one of the most important components in determining the sound quality of the audio equipment, because it is necessary to extract a greater amount of information from the high-resolution audio source data and convert it into an analog signal. All along, ROHM's audio product development has paid great attention to sound quality. For example, based on 50 years of experience in the development of audio IC products, we have established a "sound quality design technology" that can fully extract the amount of audio source information, and introduced high-quality sound processor ICs and high-quality audio power supply ICs. Among them, the performance of the "MUS-IC™" series has been highly praised by customers, and is being used in high-quality audio equipment by more and more customers.

     "BD34301EKV", as the DAC chip in the high-end series "MUS-IC™" of audio IC launched by ROHM, has paid great attention to "spatial sound effect", "sense of scale" and "quietness" when enjoying classical music at the beginning of development. Important audio performance. With ROHM's own sound quality design technology, in the process of designing the signal processing circuit, which is the key to sound quality, the method of designing the circuit while confirming the sound quality has successfully achieved the target sound quality. At the same time, low noise (SN ratio) and low distortion rate (THD+N characteristics), as important characteristics of audio products, have also reached an extremely high level in the industry (SN ratio 130dB, THD+N-115dB), and their performance is very suitable for high sound quality. Audio equipment. In addition, the built-in digital filter, which is the main function of the digital signal processing circuit, adopts a customizable specification, which contributes to the realization of the ideal sound quality effect pursued by audio equipment manufacturers.
