Description

The AK4522 has a dynamic range of 100dB and is well-suited middle-range MD, surround system,musical instruments and car audio. Signal inputs and outputs are single-ended. The DAC outputs are analog filtered to remove out of band noise. External components are minimized. The AK4522 is available in a small 24pin VSOP package, which will reduce system space.
