AK4393 is a high performance stereo DAC for the 96kHz sampling mode of DAT,DVD including a 24bit digital
filter. The AK4393 introduces the advanced multi-bit system for
the wider dynamic range, while keeping much the same superior distortion characteristics as conventional
Single Bit way. In the AK4393, 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. The operating voltages support analog=5V and digital=3.3V, so it is easy to I/F
with 3.3V logic IC.
