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.
