3) Using AKM’s evaluation board for ADC
To evaluate AK4380 with analog input, the AKM’s evaluation board for ADC can be used. MCLK, BICK and
LRCK are supplied from clock generator on the AKD4380, and analog signal is A/D converted and send to
AKD4380 through PORT2(ADC/ROM). In case of using external master clock through a BNC connector, select
“BNC” on JP12(MCLK) and short JP13(XTE).
