AK5397
32-Bit Stereo Premium ADC
1. Genaral Description
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 Pro^TM family. The AK5397
integrates a newly developed circuit by VELVET
SOUND^TM technology achieving rich sound field
and bass representation that realizes a music
playback experience with less distortion. The
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.
