[AK5392]
AK5392
Enhanced Dual Bit
∆Σ
24Bit ADC
General Description
The AK5392 is a 24bit, 128x oversampling 2ch A/D Converterfor professional digital audio systems. The modulator
in the AK5392 uses the new developed Enhanced Dual Bit architecture. This new architecture achieves the wider
dynamic range, while keeping much the same superior distortion characteristics as conventional Single Bit way. The
AK5392 performs 116dB dynamic range, so the device is suitable for professional studio equipments such as digital
mixer, digital VTR etc.
