1. Evaluation Board Manual Operation sequence
1) Set up the power supply lines. [VP] (Orange) = 11.4 12.6V (typ. 12V, for VP pin) [VD] (Red) = 4.75 5.25V (typ. 5.0V, for VD pin) [VVD] (Red) = 4.75 5.25V (typ. 5.0V, for VVD1 pin, VVD2 pin) [VCC] (Red) = 5.0V (for digital logic) [AGND] (Black) = 0V (for analog ground: VSS, VVSS) [DGND] (Black) = 0V (for digital ground) Each supply line should be distributed from the power supply unit. 2) Set-up jumper pins. (See the followings.) 3) Power on. The AK4707 should be reset once bringing SW1 "L" upon power-up.
Jumper pins set up
[JP1] (GND): Analog ground and Digital ground OPEN: Separated SHORT: Common. (The connector "DGND" can be open.) [JP2] (VD): Regulator +5V or VD connector OPEN: VD pin is supplied from VD connector. SHORT: VD pin is supplied to regulator +5V. (The connector "VD" can be open.) [JP3] (VVD): VD connector or VVD connector OPEN: VVD1 and VVD2 pins are supplied from VVD connector. SHORT: VVD1 and VVD2 pins are supplied from VD connector. (The connector "VVD" can be open.) [JP4] (VCC): VVD connector or VCC connector OPEN: Logic voltage is supplied from VCC connector. SHORT: Logic voltage is supplied form VVD connector. (The connector "VCC" can be open.) The regulator can be supplied 5.0V to all circuits by shorting JP2, JP3 and JP4 and supplying 12V to VP connector.

The function of the toggle SW
[SW1] (PDN): Resets the AK4707. Keep "H" during normal operation.
The indication content for INT pin
Changes of the 08H status can be monitored via the TEST1 (INT). The INT pin is the open drain output and goes "L" for 2s (typ.) when the status of 08H is changed.
Serial Control
The AK4707 can be controlled via the printer port (parallel port) of IBM-AT compatible PC. Connect PORT1 (CTRL) with PC by 10-line flat cable packed with the AKD4707-A. The control software packed with this evaluation board supports I2C control only.
