GENERAL DESCRIPTION

The AK4480 is a 32-bit DAC, which corresponds to Blu-ray Disc systems.An internal circuit includes newly developed 32bit Digital Filter for better sound quality achieving low distortion characteristics and wide dynamic range. The AK4480 has full differential SCF outputs, removing the need for AC coupling capacitors and increasing performance for systems with excessive clock jitter. The AK4480 accepts 216kHz PCM data and 1-bit DSD data, ideal for a wide range of applications including Blu-ray Discs and SACDs.
