1.
Grounding and Power Supply Decoupling
The AK5702 requires careful attention to power supply and grounding arrangements. AVDD and DVDD are usually
supplied from the system’s analog supply. If AVDD and DVDD are supplied separately, the power-up sequence is not
critical. VSS1 and VSS2 of the AK5702 should be connected to the analog ground plane. System analog ground and
digital ground should be connected together near to where the supplies are brought onto the printed circuit board.
Decoupling capacitors should be as near to the AK5702 as possible, with the small value ceramic capacitor being the
nearest.
2.
Voltage Reference
VCOM is a signal ground of this chip. A 2.2
μ
F electrolytic capacitor in parallel with a 0.1
μ
F ceramic capacitor attached
to the VCOM pin eliminates the effects of high frequency noise. No load current may be drawn from the VCOM pin. All
signals, especially clocks, should be kept away from the VCOM pin in order to avoid unwanted coupling into the
AK5702.
3.
Analog Inputs
The analog inputs are single-ended or full-differential and input resistance is 60k
Ω
(typ)@MGAIN1-0 bits = “00”, 30k
Ω
(typ)@MGAIN1-0 bits = “01”, “10” or “11”. The input signal range scales with 0.6 x AVDD Vpp(typ)@MGAIN 1-0 bits
= “00” centered around the internal common voltage (0.5 x AVDD). Usually the input signal is AC coupled using a
capacitor. The cut-off frequency is fc = 1/ (2
π
RC). The ADC output data format is 2’s complement. The DC offset
including the ADC’s own DC offset is removed by the internal HPF (fc=3.4Hz@ HPF1-0 bits = “00”, fs=44.1kHz). The
AK5702 can accept input voltages from VSS1 to AVDD at single-ended.
