Other Parts Discussed in Thread: AFE5832, , AFE5808, AFE5816,
Hi,
I have seen that some datasheets from advanced ultrasound front-ends like the AFE5816 and AFE5832 specifies that INPx and INMx pins must be protected in the PCB layout keeping an isolation area from the ground and power planes underneed them. However, it seems this area is not requiered in the AFE5808A, or at least it has not been conidered in the AFE5808AEVM layout. Is it mandatory/recommended to keep this isolation with this part too? If so, is this area required both in power and ground planes, or only in power planes, like appear in the AFE5808 datasheet?
Best regards,
C.J.
