GENERAL DESCRIPTION
The AK4528 is a high performance 24bit CODEC for the 96kHz recording system. The ADC has an
Enhanced Dual Bit architecture with wide dynamic range. The DAC uses the new developed Advanced
Multi Bit architecture and achieves low outband noise and high jitter tolerance by use of SCF (switched
capacitor filter) techniques.
