Applications
BD3822FS and BD3824FS are the audio selectors with internal input selector, gain amp, ALC and power save ON/OFF functions.
BD3822FS contains the 1/2 power compression amp for level meter and 2ch volume. BD3824FS contains the line amp.
BD3822FS and BD3824FS unify the board pattern by pin compatible, and can be used individually as a high-end and low-end
model.
