3) Setup the Audio I/F Evaluation Mode.

In case of using the AK4118A when evaluating the AK5736, the audio interface format of the AK5736and

AK4118A must be matched.

Refer to the datasheet for audio interface format of AK5736, and audio interface format of AK4118A. (Table 4)

The AK4118A operates at sampling frequency of 32 kHz or more. If the sampling frequency is lower than 32 kHz,

please use other mode. Refer to the datasheet for register setting of the AK5736.

(1) Evaluation of A/D using DIT of AK4118A.

CONTROL SOFTWARE MANUAL

■ Evaluation Board and Control Software Settings

1. Set an evaluation board properly.

2. Connect Evaluation board to PC with USB cable.

USB control is recognized as HID (Human Interface Device) on the PC.

When it can not be recognized correctly please reconnect Evaluation board to PC with USB cable.

3. Proceed evaluation by following the process below.

[Support OS]

Windows 7 (32bit) / 10 (64bit)

■ Operation Screen

1. Start up the control program following the process above.

2. After the evaluation board’s power is supplied, the AK5736 must be reset once.

(Pushing [Port Reset] button, and power up AK5736 by [PDN : H] button.)
