AK4523 General Description

The AK4523 has a dynamic range of 100dB and is well-suited middle-range MD, surround system,musical instruments and car audio. Signal inputs and outputs are single-ended. The DAC outputs are analog filtered to remove out of band noise. External components are minimized.

AK4524 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.
