[AK5397] AK5397
32-Bit Stereo Premium ADC
1. Genaral Description
class leading performance with a maximum 768kHz PCM output is supported for digital output and newly developed 32-bit digital filters are integrated for the best sound quality. The AK5397 is suitable for digital video recorders and high quality sound studio mixers for recording and editing high-resolution sound sources. The AK5397 is a high performance 32-bit stereo ADC that achieves class leading performance of 127dB dynamic range for stereo output. This is a flagship addition to AKM's VERITA series of product in the Audio 4 ProTM family. The AK5397 integrates a newly developed circuit by VELVET SOUNDTM technology achieving rich sound field and bass representation that realizes a music playback experience with less distortion. The 2.
