AK4497  
Quality Oriented 32-Bit 2ch DAC  
1.General Description  
The AK4497 is a new generation Premium 32-bit 2ch DAC with VELVET SOUNDTM technology,  
achieving industry’s leading level low distortion characteristics and wide dynamic range. The AK4497  
integrates a newly developed switched capacitor filter “OSR Doubler”, making it capable of supporting  
wide range signals and achieving low out-of-band noise while realizing low power consumption.  
Moreover, the AK4497 has six types of 32-bit digital filters, realizing simple and flexible sound tuning in  
wide range of applications. The AK4497 accepts up to 768kHz PCM data and 22.4MHz DSD data, ideal  
for a high-resolution audio source playback that are becoming widespread in network audios,  
USB-DACs and Car Audio Systems.  
Application: AV Receivers, CD/SACD player, Network Audios, USB DACs, USB Headphones, Sound  
Plates/Bars, Measurement Equipment, Control Systems, Public Audios (PA), IC-Recorders,  
Bluetooth Headphones, HD Audio/Voice Conference Systems
