AK4480

High Performance 114dB 32-Bit DAC

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.
