AKD4343-B
AK4343 Evaluation board Rev.0
GENERAL DESCRIPTION
The AKD4343-B is an evaluation board for the AK4343, Stereo DAC with built-in HP/RCV/SPK amplifier.
The AKD4343-B has the interface with AKM’s ADC evaluation boards. Therefore, it’s easy to evaluate the
AK4343. The AKD4343-B also has the digital audio interface and can achieve the interface with digital
audio systems via opt-connector.

„ Operation sequence
1) Set up the power supply lines.
[VCC]
(red)
= 5.0V (or 3.3V)
[AGND] (black)
= 0V
[DGND] (black)
= 0V
Each supply line should be distributed from the power supply unit.
When the power is supplied to the AK4343 via the regulator, JP21 should be set to “REG” side and VCC
should be 5.0V.<default> (When the power is supplied from VCC jack to the AK4343 directly, JP21 should
be set to “VCC” side and VCC should be 3.3V.)
2) Set up the evaluation mode, jumper pins. (See the followings.)
3) Power on.
The AK4343 and AK4114 should be reset once bringing SW1 “L” upon power-up.
And the AK7830 should be reset once bringing SW2(SPK_PDN) “L” upon power-up.
„ Evaluation mode
(1) Slave mode
(1-1) Evaluation of Playback block (HP, SPK, LOUT) using DIR of AK4114 <Default>
(1-2) All interface signals including master clock are fed externally.
The AK4114’s audio interface format is fixed to LJ compatible.

The AK4114 operates at fs of 32kHz or more. If the fs is slower than 32kHz,
any other evaluation mode without using DIR should be used.

„ Serial Control
The AK4343 can be controlled via the printer port (parallel port) of IBM-AT compatible PC. Connect PORT4
(CTRL) with PC by 10 wire flat cable packed with the AKD4343. When I2C bus mode is used, PORT4 should be
directly connected to the I2C bus on the system. JP13,14 and 15 should be set to I2C bus mode to control the
AK7830.

• AKM assumes no liability for infringement of any patent, intellectual property, or other right in the

used here:
(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
