AK4393

Advanced Multi-Bit 96kHz 24-Bit DS DAC

GENERAL DESCRIPTION

The 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 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 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.
