AFE4300: AFE4300 IQ mode to test impedance

Jason Chen

Part Number: AFE4300

Hello TI team

I am using AFE4300 to create an impedance testing motherboard, and the hardware has been referenced in the AFE4300 Development Guide. The circuit should be fine; The current issue I am facing is that by configuring the AFE4300 register and using IQ mode to test impedance, I have read the I value, Q value, and impedance value that are constantly changing. How should I proceed to the next step of calculating the impedance of the resistor I am connected to?

Hi Jason,

Welcome to the E2EChina forum.

Since AFE4300 is an NDA product and is not supported in public forum, please send an English email to biosensing_afe-support@list.ti.com for technical support. This product is supported by a team of engineers in the United States and requires communication in English.

Hi Jason,

I'm sorry to let you wait so long and no one replies to your email. Now I suggest that you post your question on the E2E Technical Forum (link:https://e2e.ti.com/support/interface-group/interface/f/interface-forum ) and state that you have sent this question to the above email and have not received a response, and that E2E Technical Forum engineers should contact you by email.

Thanks,

Amy
