AK4524 24 bit 96kHz AUDIO CODEC
GENERAL DESCRIPTION
The AK4524 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.The AK4524 has an input PGA and is well suited MD, DVTR system and
musical instruments.
