AK4522  
20Bit Stereo ∆Σ ADC & DAC  
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.
