Introduction

AI Translation

AK4490 is a new generation Premium 32-bit 2ch DAC with new technologies, achieving industry’s leading level low distortion characteristics and wide dynamic range. The AK4490 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 AK4490 has five types of 32-bit digital filters, realizing simple and flexible sound tuning in wide range of applications. The AK4490 accepts up to 768kHz PCM data and 11.2MHz DSD data, ideal for a high-resolution audio source playback that are becoming widespread in network audios, USB-DACs and Car Audio Systems.
