„ Master Mode and Slave Mode
The M/S pin selects either master or slave mode. M/S pin = “H” selects master mode and “L” selects slave mode. The
AK5365 outputs BICK and LRCK in master mode. In slave mode, MCLK, BICK and LRCK are input externally.
BICK, LRCK
Slave Mode
BICK = Input
LRCK = Input
Master Mode
BICK = Output
LRCK = Output

„ Digital High Pass Filter
The ADC has a digital high pass filter for DC offset cancellation. The cut-off frequency of the HPF is 1.0Hz
(@fs=48kHz) and scales with sampling rate (fs).
