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.
