Reference current setting pin
O Connect this pin to Analog ground via a 4.7 kohm ( <= 1 % accuracy ) resistor.
This pin becomes Hi-Z output at power-down mode.
internal negative reference voltage for AD converter
O
- connect this pin to Analog ground via a 0.1 uF or larger capacitor.
- there is a case when this pin becomes Hi-Z output at power-down.
- Do not use this as a reference voltage source for external circuit(s).
O internal positive reference voltage for AD converter
O
- connect this pin to Analog ground via a 0.1 uF or larger capacitor.
- there is a case when this pin becomes Hi-Z output at power-down.
- do not use this as a reference voltage source for external circuit(s).
internal common voltage for AD converter
O
- connect this pin to Analog ground via a 0.1 uF or larger capacitor.
- there is a case when this pin becomes Hi-Z output at power-down.
- do not use this as a reference voltage source for external circuit(s).

I : input pin
O : output pin
I/O : input / output pin
P : power supply pin
G : ground pin
note ) the AK8855 starts to output after it is reset.
When no signal is input, Black level data ( Y = 0x10, Cb/Cr = 0x80 ) is output.
