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.
