n Operation sequence
(1) Set up the power supply lines.
[+12V] (orange jack) = +12 ∼ +15V
[-12V] (blue jack)
= -12 ∼ -15V
[AGND] (black jack) = 0V
[DGND] (black jack) = 0V
Each supply line should be distributed from the power supply unit.
±12V are supplied to analog interface.
+12V is regulated to +5V and +3.3V by regulators(T1,T2).
+5V is supplied to digital interface, AK4628 and TVDD of AK4112B.
+3.3V is supplied to AVDD and DVDD of AK4112B and TVDD of AK4628.
(2) Set up the evaluation mode and jumper pins. (See p.6.)
(3) Power on.
