AK4490
Premium 32-Bit 2ch DAC
1. General Description
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.
Application: AV Receivers, CD/SACD player, Network Audios, USB DACs, USB Headphones, Sound
Plates/Bars, Car Audios, Automotive External Amplifiers, Measurement Equipment, Control
Systems, Public Audios (PA), Smart Cellular Phones, IC-Recorders, Bluetooth Headphones, HD
Audio/Voice Conference Systems
