GENERAL DESCRIPTION
The AK4356 is a high performance six channels DAC corresponding to 96kHz sampling mode of DVD.
Two channels of them can operate up to 192kHz sampling fully correspond to DVD-Audio standards. The
AK4356 introduces the advanced multi-bit architecture for
DS
modulator. This new architecture achieves
the wider dynamic range, while keeping much the same superior distortion characteristics as
conventional Single Bit way. In the AK4356, the analog outputs are filtered in the analog domain by
switched-capacitor filter (SCF) with high tolerance to clock jitter. The analog outputs are full differential
output, so the device is suitable for hi-end applications.
