MDIF1 bit
ASAHI KASEI
The AK4343 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).
The AK4343 has input selector. When MDIF1 and MDIF2 bits are “0”, INL1-0 and INR1-0 bits select LIN1/LIN2/LIN3
and RIN1/RIN2/RIN3, 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. When full-differential input
is used, the signal should not be input to the pins marked by “X” in Table 20.
