Product Summary

The AK4394VF is a high performance stereo DAC for the 192kHz sampling mode of DVD-Audio including a 24bit digital filter. The AK4394VF introduces the advanced multi-bit system 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 AK4394VF, the analog outputs are filtered in the analog domain by switched-capacitor filter(SCF) with high tolerance to clock jitter.
