Digital High Pass Filter
The ADC has a digital high pass filter for DC offset cancellation. The cut-off frequency of the HPF is 0.9Hz
(@fs=44.1kHz) and scales with sampling rate (fs). When PMADL bit = “1” or PMADR bit = “1”, the HPF of ADC is
enabled but the HPF of DAC is disabled. When PMADL=PMADR bits = “0”, PMDAC bit = “1”, the HPF of DAC is
enabled but the HPF of ADC is disabled.
MIC/LINE Input Selector
The AK4647 has input selector. When MDIF1 and MDIF2 bits are “0”, INL and INR bits select LIN1/LIN2 and
RIN1/RIN2, respectively. When MDIF1 and MDIF2 bits are “1”, LIN1, RIN1, LIN2 and RIN2 pins become IN1
, IN1+,
IN2+ and IN2
pins respectively. In this case, full-differential input is available (Figure 22). When full-differential input
is used, the signal should not be input to the pins marked by “X” in.
