GENERAL DESCRIPTION

The AK4393 is a high performance stereo DAC for the 96kHz sampling mode ofDAT, DVD including a 24bit digital filter. The AK4393 introducesthe advanced multi-bit system for ΔΣmodulator. This new architecture achieves the widerdynamic range, while keeping muchthe 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.
