Please give the suggested circuits for the ADC channels protection circuits for the ADuCM361 micro controller.
Thanks in advance.
Usually the normal ADC input filters, depending on the system requirements, are sufficient.
Means some kind of RC filter.
Some good design hints can be found on or WebSite for general Mixed-Signal-Design.
Mixed Signal and DSP Design Techniques
In harsh environments also additional protection may be required.
A good starting point here is the PLC Demo System..
I'm sorry for the delay. I have moved your question on the ADuCM361 to the ADuC Cortex M3 community. If you still need an answer, someone in this community should be able to assist you.
Thanks for your reply.
I've to use this in harsh environment. So I require protection circuit from lightening, high & Reverse voltages of +/-14V DC.
