Description

The AK4393VF is a high performance stereo DAC for the 96kHz sampling mode of DAT, DVD including a 24bit digital filter. It introduces the advanced multi-bit system for ∆Σmodulator, achieving a wider dynamic range while maintaining superior distortion characteristics. The analog outputs are filtered in the analog domain by a switched-capacitor filter (SCF) with high tolerance to clock jitter. With full differential output, it is suitable for hi-end applications. The operating voltages support analog 5V and digital 3.3V, making it easy to interface with 3.3V logic IC.
