The AK5392 is a 24bit, 128x oversampling 2ch A/D Converterfor professional digital audio systems. The modulator
in the AK5392 uses the new developed Enhanced Dual Bit architecture. This new architecture achieves the wider
dynamic range, while keeping much the same superior distortion characteristics as conventional Single Bit way. The
AK5392 performs 116dB dynamic range, so the device is suitable for professional studio equipments such as digital
mixer, digital VTR etc.

... VCOM is a common voltage of the analog signal. In order to eliminate the effects of high frequency noise, a 0.22uF ceramic capacitor should be connected as near to the VCOM pin as possible. And all signals, especially clocks, should be kept away from the VCOM pin in order to avoid unwanted coupling into the AK5392. No load current may be drawn from the VCOM pin. ...
