AK4399 is a 32-bit DAC that corresponds to DVD-Audio systems. An internal circuit includes newly developed 32bit Digital Filter for better sound quality achieving low distortion characteristics and wide dynamic range. The AK4399 has full differential SCF outputs, removing the need for AC coupling capacitors and increasing performance for systems with excessive clock jitter. The AK4399 accepts 192kHz PCM data and 1-bit DSD data, ideal for a wide range of applications including Blu-Ray, DVD-Audio and SACD.
The AK4399 is a 32‑bit digital‑to‑analog converter designed for high‑resolution audio applications such as DVD‑Audio, Blu‑Ray, and SACD. It features a 32‑bit digital filter, differential SCF outputs, and supports both PCM and 1‑bit DSD data streams.
The datasheet provides full pin‑out information, absolute maximum ratings, recommended operating conditions, and analog performance characteristics including THD+N, dynamic range, and load requirements. It also includes handling instructions for unused pins and revision history.
