AK4730-100W Evaluation Board Rev.4
GENERAL DESCRIPTION The AKD4730-100W is the evaluation board of AK4730, which is one chip modulator built in two channel PWM Modulators and Pre-Drivers of MOSFETs for Class-D Amplifier. It has the interface of the evaluation board of AKM's ADC, it is possible to evaluate it easily. The AKD4730 also has the digital audio interface and can achieve the interface with digital audio systems via opt-connector. Ordering guide
AKD4730-100W --- AK4730-100W Evaluation Board (Cable for connecting with printer port of IBM-AT compatible PC and control software are packed with this.) This control software can't operate on Windows NT. FUNCTION MOSFET drivers is built in Compatible with 2 types of interface - The optical input - Direct interface with AC3 decoder by 10pin header 10pin header for serial control interface

VP1, 2,3 pins of AK4730 Should be connected MVDD pin of AK4730, the Should be connected regulator and so on. All GND of AK4730 Should be connected Table 1. Wiring of the power supply
Please wire the power supply carefully. (Divide wiring from each power supply) 2) Setup of each clocks to AK4730 The input method of the clocks to AK4730 has two kinds of methods. One method is from the mounted AK4114, another is from the external inputs. These setting is selected by the jumpers of JP1(MCLK), JP2(BICK), JP3(LRCK), JP4(SDATA). (see the following Figures)

1. Set up the AKD4730-100W according to above mentioned setting. 2. Connect IBM-AT compatible PC with AKD4730-100W by 10-line type flat cable (packed with AKD4730). Take care of the direction of 10pin header. (Please install the driver in the CD-ROM-disk when this control software is used on Windows 2000/XP. Please refer "Installation Manual of Control Software Driver by AKM device control software". In case of Windows95/98/ME, this installation is not needed. This control software does not operate on Windows NT.) 3. Insert the CD-ROM-disk labeled "AKD4730-100W Evaluation Kit" into the CD-ROM-disk drive. 4. Access the CD-ROM-disk drive and double-click the icon of "akd4730_3.exe" to set up the control program. 5. Then please evaluate according to the followings.
Operation flow
Keep the following flow. 1. Start a control program in accordance with the above. 2. Next, it should input and output data properly, and evaluate it.

Attention on the operation
In the case that the function of "Output-Short Protection" is used Write "1" to PW bit after PROT bit was written "1". In the case that the function of "Adaptive Dead-Time Control" is used Write "1" to ADTC bit after PW bit was written "1". If you set up Function1 or Function2 dialog, input data to all boxes. Attention dialog is indicated if you input data or address that is not specified in the datasheet or you click "OK" button before you input data. In that case set up the dialog and input data once more again. These operations does not need if you click "Cancel" button or check the check box.

Note: When PDN pin is "L", it is impossible to write the data to all registers. It is initialized. Do not write the data to Addr.10H~1FH.
* The setting of the registers of Red character as the above Addr."06H~09H" is recommended to Dead-Time (for MOSFET Array SLA5097) on the AKD4730-100W evaluation board. * When the function of ADTC is evaluated, set up the power supply (Vp) to 48V.
