AFE58JD18: Common ground?

Gregory Duperon

Part Number: AFE58JD18

The input to the AFE is single ended and my understanding is that INM connects via a capacitor to a “ground” that is shared with the input transducer.

Should this “ground” be connected to the AVSS as well?

Thanks for using 58JD18!

Yes. you can connect the GND to AVSS. you can also assign the INM cap ground to a seperate GND, then connect it to AVSS via ferrite bead or 0ohm if you want to seperate this xducer GND for noise concerns.

Thanks!
