GENERAL DESCRIPTION

The AK5383 is a 24bit, 128x oversampling 2ch A/D Converter for professional digital audio systems. The

modulator in the AK5383 uses the new developed Enhanced Dual Bit architecture. This new architecture

achieves the wide dynamic range, while keeping much the same superior distortion characteristics as

conventional Single Bit way. The AK5383 performs 110dB dynamic range, so the device is suitable for

professional studio equipment such as digital mixer, digital VTR etc.
