Overview

The AK4454 is a 32-bit 4ch Premium DAC, which achieves industry’s best low distortion characteristics by a newly developed low distortion technology. It corresponds to a 768kHz PCM input and an 11.2MHz DSD input at maximum, suitable for play backing high resolution audio sources that are becoming widespread in network audios, USB-DACs and Car Audio Systems. In addition, “OSR-Doubler” technology is newly adopted, making the AK4454 capable of supporting wide range signals and achieving low out-of-band noise while realizing low power consumption. Moreover, the AK4454 has five types of 32-bit digital filters, realizing simple and flexible sound making in wide range of applications.
