High Performance 120dB 24-Bit 4ch DAC
GENERAL DESCRIPTION
AK4413 is a 24-bit DAC, which corresponds to BD systems. An internal circuit includes newly developed
24bit Digital Filter for better sound quality achieving low distortion characteristics and wide dynamic
range. The AK4413 has full differential SCF outputs, removing the need for AC coupling capacitors and
increasing performance for systems with excessive clock jitter. The AK4413 accepts 216kHz PCM data,
ideal for a wide range of applications including DVD-Audio.
