AK4456
115dB 768kHz 32-bit 6ch Premium DAC
1. General Description
AK4456 is a 32-bit DAC which corresponds to DVD-audio systems. An internal circuit includes newly
developed 32-bit Digital Filter for better sound quality achieving low distortion characteristics and wide
dynamic range. The AK4456 has full differential SCF outputs, removing the need for AC coupling capacitors
and increasing performance for systems with excessive clock jitter. The AK4456 accepts 768kHz PCM data
and 1-bit DSD data, ideal for a wide range of applications including DVD-Audio, SACD and car audio
surround system.
