Grounding and Power Supply Decoupling
VD, VP, VVD1, VVD2, VSS and VVSS should be supplied from analog supply unit with low impedance and be
separated from system digital supply. An electrolytic capacitor 10
μ
F parallel with a 0.1
μ
F ceramic capacitor should be
attached to these pins to eliminate the effects of high frequency noise. The 0.1
μ
F ceramic capacitor should be placed as
near to VD (VP, VVD1, VVD2) as possible.
Voltage Reference
Each DVCOM/PVCOM are common voltage of this chip. An electrolytic capacitor 10
μ
F parallel with a 0.1
μ
F ceramic
capacitor should be attached to these VCOM pins to eliminate the effects of high frequency noise. No load current should
be drawn from these VCOM pins. All signals, especially clocks, should be kept away from these VCOM pins in order to
avoid unwanted coupling into the AK4708.
Analog Audio Outputs
The analog outputs are also single-ended and centered on 5.6V(typ.). The output signal range is typically 2Vrms .
