ROHM Semiconductor BD34302EKV MUS-IC™ Series 32-Bit Stereo Audio DAC

ROHM Semiconductor BD34302EKV MUS-IC™ Series 32-Bit Stereo Audio DAC is developed for high-quality audio that integrates ROHM's exceptional sound quality design technology. The DWA enhances THD performance and supplies higher resolution and better natural sound quality with HD (High-Definition) monaural mode. Additionally, the ROHM BD34302EKV has an automatic mode-switching function that allows users to easily switch between PCM/DSD and different sampling frequencies.
