Dear Specialists,

My customer is interested in ADS131A04 and has a question.

I would be grateful if you could advise.

There are ADS131A , ADS131M0x, and ADS131E0x series.

I could not understand the difference.

What are the differences between the ADS131A0x, ADS131M0x, and ADS131E0x?

Could you provide comparison table?
