Question

Hi, What is the recommended method for ESD/EMC protection on the analogue input pins on the AD7150 
 Our design uses a plug and socket for the analogue connections 
 Thank you

Hi, 
 Can you clarify the correct part number please? The title mentioned AD7195 but the statement mentioned AD7150? 
 If AD7195, we have an application note that did some EMC testing (radiated immunity) on AD7192 (co-family of AD7195 without the AC excitation). The application note is available on the AD7192 Product Page documentation section. Here, the AD7192 were used as part of a weighscale design. However, this might also help you in your application as it shares a lot of general information such as using the reference circuit for filter design, using a common gnd plane on the PCB board, placement of components about the ADC, etc. that might be appropriate in your system. 
 For ESD, I think this FAQ may help you.
