GENERAL DESCRIPTION

The AK4395 is a high performance stereo DAC for the 192kHz sampling mode of DVD-Audio including a

24bit digital filter. The digital filter has high stopband attenuation with 110dB or more that reduces wide band aliasing noise. The AK4395 introduces the advanced multi-bit system for ∆Σmodulator. This new architecture achieves the wider dynamic range, while keeping much the same superior distortion characteristics as conventional Single-Bit way. The analog outputs are filtered in the analog domain by

switched-capacitor filter (SCF) with high tolerance to clock jitter. The AK4395 also includes digital volume, so the device is suitable for multi-channel audio system.
