We are designing a control handle with proximity detection, meaning, the user must hold or be in close proximity of the control handle to be able to activate it. Functionally I can not seem to see the difference between AD7150 and AD7156, where are the differences?
The Cin and Exc sensor input signals are required to be shielded, practically this is a problem when using PFC/FFC cable to connect the sensors. Do these signals to be separated in the FPC/FFC cable with a shield inbetween them as well? Any technical information available about this?
As this is a medical device, we need to take great care about ESD and EMC protection, is there more information about this as well?
