ROHM Unveils Revolutionary Second-Generation DAC for High-Resolution Audio Experience
ROHM, a leading semiconductor manufacturer, has introduced its new 32-bit D/A converter IC, known as the BD34302EKV, which is a pivotal addition to its acclaimed MUS-IC™ series. This latest DAC chip aims to provide unparalleled high-resolution audio playback, elevating the listening experience with advanced features engineered for sound perfection.
With a rich legacy of over 50 years in sound design and high-fidelity audio solutions, ROHM's expertise translates directly into the BD34302EKV. This chip builds on the foundational success of its predecessor, the BD34301EKV, which is widely recognized in high-end audio applications. Retaining the design philosophy of delivering natural and flat sound, the BD34302EKV integrates innovative technologies to reproduce audio as close to the original performance as possible.
A key highlight of the BD34302EKV is its adeptness in rendering the three essential elements of sound: spatial reverberation, perceived quietness, and dynamic range. By reproducing sound with authenticity, this new DAC chip successfully conveys the very texture of musical instruments, allowing listeners to immerse themselves entirely in the audio experience. This not only enhances enjoyment for casual listeners but also meets the discerning standards of audiophiles seeking premium-quality sound.
One of the technical improvements in this second-generation DAC is the implementation of a new data-weighted averaging (DWA) algorithm. This upgrade plays a crucial role in achieving a Total Harmonic Distortion plus Noise (THD+N) rating of -117dB, with a remarkable THD of -127dB. These metrics indicate that the BD34302EKV can deliver sound quality that is discernibly richer and more intricate, effectively capturing the nuances of each note and sound.
Additionally, the chip boasts a signal-to-noise ratio (SNR) of 130dB, ensuring that noise performance aligns with flagship standards required for high-quality audio playback. The device supports sampling frequencies of up to 1,536kHz, enabling users to utilize the high-precision capabilities of digital signal processors (DSPs) to their fullest potential.
The introduction of a proprietary HD monaural mode is another standout feature of the BD34302EKV. In this mode, each audio channel is allocated its own DAC chip, resulting in a sound profile that is smoother and more natural. ROHM's commitment to intricate craftsmanship is evident in the meticulous selection of the optimal bonding wire material used in the terminals, which ensures accurate sound transmission and highlights the natural texture of musical notes.
ROHM’s dedication to sound quality design is not just a matter of improving metrics but significantly enhances the listening experience. The MIN-IC™ series continues to push the envelope in audio technology, offering advanced solutions sought after by manufacturers focused on high-performance audio equipment.
For music lovers and professionals alike, the BD34302EKV represents an evolution in audio technology, demonstrating how advancements in semiconductor technology can directly enhance musical experiences. The product video showcasing the capabilities of the BD34302EKV can be found online, highlighting its potential impact on the audio landscape.
As consumers increasingly seek high-resolution audio for both personal enjoyment and professional applications, ROHM’s latest DAC chip positions itself as a leading choice in the market, fulfilling the demands of modern audio enthusiasts. This cutting-edge technology not only underscores ROHM's commitment to innovation in the audio sector but also sets the stage for future advancements that will continue to refine and elevate sound quality across various listening environments.
