Overview
[AK4414] AK4414 High Performance 120dB 32-Bit 4ch DAC GENERAL DESCRIPTION AK4414 is a 32-bit DAC, which corresponds to BD systems.
An internal circuit includes newly developed 32bit Digital Filter for better sound q uality achiev ing low distortion charac teristics and wide dynamic range.
The AK4414 has full differential SCF outputs, removing the need for AC coupling capacitors a nd increasing performance for systems with excessive clock jitter.
The AK4414 accepts 216kHz PCM d ata and 1-bit DSD data, ideal for a wide range of applications including DVD-Audio and SACD.
