„ 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.) <Default>
[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.) <Default>
[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.) <Default>
[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.) <Default>
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
2µs (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.

(a) A hazard related device or system is one designed or intended for life support or maintenance of safety or
for applications in medicine, aerospace, nuclear energy, or other fields, in which its failure to function or
perform may reasonably be expected to result in loss of life or in significant injury or damage to person or
property.
(b) A critical component is one whose failure to function or perform may reasonably be expected to result,
whether directly or indirectly, in the loss of the safety or effectiveness of the device or system containing it,
and which must therefore meet very high standards of performance and reliability.
• It is the responsibility of the buyer or distributor of an AKM product who distributes, disposes of, or otherwise
places the product with a third party to notify that party in advance of the above content and conditions, and the
buyer or distributor agrees to assume any and all responsibility and liability for and hold AKM harmless from any
and all claims arising from the use of said product in the absence of such notification.
