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