Serial Bit Clock 2 Pin
I/O
(MSELN bit = “L”, default)
Serial Data Input 3 Pin
(MSELN bit = “H”)
I Master Clock Pin
SPI I/F Chip Select N Pin
I
During power-down state or when μP I/F are not in use, leave this pin
“H” level.
O
Serial Data Output Pin for SPI I/F
This pin outputs “Hi-Z” during power-down state.
I/O
Serial Data In/Output Pin for I²C I/F
This pin outputs “Hi-Z” during power-down state.
I Serial Data Clock Input Pin for SPI I/F
I Serial Data Clock Input Pin for I²C I/F
I Serial Data Input Pin for SPI I/F
I²C I/F Mode Select Input Pin
I
I2CFIL = “L”: Fast Mode (400kHz)
I2CFIL = “H”: Fast Mode Plus (1MHz) (should be fixed to TVDD)
Power-down N Pin
I
Use this pin to power down the AK4601.
The PDN pin should be held “L” when power is supplied.
