AFE4432: Questions About ADC_READY and I²C Design and NDA PCB design

Tool/software:

Hello,

I have a couple of questions regarding my design and would appreciate your guidance:

  1. Does the ADC_READY signal need a pull-up resistor, or is it handled internally?

  2. Is it acceptable to connect the I2C SELECT to the same supply as the RX (receiver) supply? This approach simplifies the fabrication of my design, but I want to confirm if it's good practice.

Additionally, I have some concerns regarding the grounding in my PCB design. Since this is covered by an NDA, is there a way to privately share my design with an engineer for review? For example, is it possible to contact someone directly via email for feedback?

Thank you for your help!

Kind regards,
Luca
