AK4522
GENERAL 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.
