■
The ADC has a digital high pass filter for DC offset cancellation. The cut-off frequency of the HPF is selected by HPF1-0
bits
■
The AK5701 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 LIN+, LIN−,
RIN− and RIN+ pins respectively. In this case, full-differential input is available
