AK4522

20Bit Stereo ΔΣ 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 SSOP package, which will reduce system space.
