AK4399  
High Performance 123dB Premium 32-Bit DAC  
GENERAL DESCRIPTION  
AK4399 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 AK4399 has full differential SCF outputs, removing the need for AC coupling  
capacitors and increasing performance for systems with excessive clock jitter. The AK4399 accepts  
192kHz PCM data and 1-bit DSD data, ideal for a wide range of applications including DVD-Audio and  
SACD.
