32-bit, 768 kHz Sampling Stereo Audio D/A Converter
BD34301EKV Evaluation Board
IC Introduction
BD34301EKV is a 32-bit Stereo Audio D/A Converter with ROHM original sound quality design, realizing excellent performance (SNR: 130 dB
(Typ), THD+N: -115 dB (Typ))*1 suitable for high-end audio. Different type sound is realized by selecting 2 kinds of digital FIR filters (Sharp Roll-
Off, Slow Roll-Off). PCM I/F supports up to 768 kHz and DSD I/F supports up to 22.4 MHz.
*1 BD34301EKV-EVK is tuned for listening evaluation. Electrical performance, External CR values are different from BD34301EKV Datasheet. (SNR: 125 dB (Typ) at Balance Output)
