ADAU1461 standalone

Hello Tim,

Well, My Deutsch is not very good, Even though I did live in Augsburg for two years! So I will try to keep my English simple so the translators can work properly.

The ADAU1461 does not have a feature that allows it to boot up on its own. Most of our other parts allow you to burn the program into an EEPROM and boot up from the EEPROM.

The USBi interface is used only to allow SigmaStudio to program and talk to the part.

If you do not have a microcontroller then you should look into using the ADAU1701. It is very similar to the ADAU1461 and is able to boot up from an EEPROM.

One other thing you should know. The ADAU1761 is the non-automotive version of the ADAU1461. So any EngineerZone articles will apply to both.

Read this post and see if this can help you. It explains how to use a microcontroller to boot up an ADAU1461. There are links inside this link to find all the information.

Let me know if you have more questions.

Thank You.

Thank You!

Do I understand correctly ADAU1401 differ is that the ADAU1701 and only in point " Automotive product " ?

Can the ADAU1401 with a I2C EEPROM AT24C08C be started in self -boot? In Datasheet the Figure 37. looks good.

I hope the translator works well :-)

many thanks

Tim

Hello Tim,

The ADAU1401A is only slightly different because of the automotive requirements. Functionally they are the same.

Yes, the ADAU1401A can boot up using an I2C EEPROM and I just looked at the AT24C08C datasheet and it seems to be compatible. But, please test it on your own before committing it to your design.

I would like to know what type of product you are planning to build?

How many units per year you plan to build?

How many years will the product expect to be manufactured?

I have a reason why I am asking these questions. I can email your directly if you need to keep details private.

Thanks,

Dave T

Hello Dave,

First I am going to build an Eval.-Board that fits my needs. (XLR-con)

After that, it is going to be a more complex project that I can explain to you in a PN.

Thank you for your help,

Tim
