Description

The AK4497EQ is a new generation premium 32-bit DAC based on AKM’s VELVET SOUND architecture that has been widely adopted by well-established high-end audio companies. High signal to noise performance is achieved by improving VELVET SOUND technology by supporting a larger current drive capability. The performance of an audio DAC using switched capacitor is expanded to the limit with the AK4497EQ. In addition, AKM has developed an original process that has greatly improved low noise performance and electric margin for audio devices, increasing data amount and enhancing original acoustic sound that can be found in the sound strength.
