AK4392
High Performance 120dB Premium 32-Bit DAC
GENERAL DESCRIPTION
AK4392 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 AK4392 has full differential SCF outputs, removing the need for AC coupling
capacitors and increasing performance for systems with excessive clock jitter. The AK4392 accepts
192kHz PCM data and 1-bit DSD data, ideal for a wide range of applications including Blu-Ray,
DVD-Audio and SACD.
