High Performance 123d B Premium 32-Bit DAC
GENERAL DESCRIPTION AK4399 is a 32-bit DAC, which 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 192k Hz PCM data and 1-bit DSD data, ideal for a wide range of applications including Blu-Ray, DVD-Audio and SACD. Features
