TPA6166A2: Android Wired Handset V1.1 compliant

Hi, Jacky,

Welcome to E2E and thank you for your interest in our products!

Could you provide these specs in order to verify if our product matches with them or if we can suggest an alternative device?

Thank you!

Best regards,

Hi, Luis,

Thanks for your response.

Actually, there is a codec - Cirrus WM8960 for our audio circuit design, we'd like to upgrade our audio circuit design with to support 4 function handsets. Attached is our audio design circuit with the WM8960 chipset 

We can change our audio design if TI can provide a total solution.

PS: Dialog have a integrated codec IC - DA7219, but, their operating temperature cannot meet out requests, our temperature specification is "-40dC ~ +85dC".

Looking forward your suggestion.

Thanks.

Hi, Luis,

Sorry, I forgotten let you know what microprocessor we used, it's NXP MIMX8ML4CVNKZAA. And, the WM8960 is the iMX8M reference design.

Thanks.

Hi, Jacky,

Thank you for the information you provided.

Excuse me for asking for more details, I would just want to understand your requirements.

- Could you list the specifications you need? I mean, do you need to replace the audio codec? If it is the case, could you provide the specifications of the audio codec that you need?

- What is the information that you require about the TPA6166A2? Is this the device that you are interested on? What are the specs that you need for this amplifier?

- Basically, if you could list the specifications and devices (probably with a block diagram) that you would like to replace, it could be also useful to get a better approach to your requirements.

Thank you.
