AK4528

[AK4528] AK4528 High Performance 24Bit 96kHz Audio CODEC 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 out-band noise and high jitter tolerance by use of SCF (switched capacitor filter) techniques.
