Overview
[AK4452] = Preliminary = AK4452 115dB 768kHz 32-bit 2ch Premium DAC 1.
General Description The AK4452 is a 32-bit 2ch 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 AK4452 capable of supporting wide range signals and achieving low out-of-band noise while realizing low power consumption.
Moreover, the AK4452 has five types of 32-bit digital filters, realizing simple and flexible sound making in wide range of applications.
Application: AV Receivers, CD/SACD Players, Network Audios, USB DACs, USB Headphones, Sound Plate/Bars, Car Audios, Automotive External Amplifiers, Measuring Instruments and Control Systems.
