... Network PCs, and to interface with audio/video controller ICs for standard PC applications. AKM’s AK4532 serial interface mode simplifies the design process on existing and new audio projects. The converters can have a range kHz. For voice mail applications, an internal 26 dB microphone preamp has been added and because of the internal input mixer, music or other sounds can easily be mixed with voice ...

... Figure 3. 2Vrms Line-level Input The AK4532 samples the analog inputs at 64fs. The digital filter rejects all noise higher than the stop band. However, the filter will not reject frequencies right around 64fs(and multiples of 64fs). Most audio signals do not have significant energy at 64fs result, two 1nF capacitors are necessary for AINFR and AINFL ...
