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.
