[AK4522]
20Bit Stereo ΔΣ ADC & DAC
GENERAL DESCRIPTION
The AK4522 has a dynamic range of 100d B 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 ponents are minimized. The AK4522 is available in a small 24pin SSOP package, which will reduce system space.
