AMC1304M25: Part problem

Part Number: AMC1304M25

Hello,

I am doing a current sensing using a shunt (25A, 100mV). I want to use AMC1304M25 for isolation. Do you a simple schematic that I can use to get the AMC working properly?. Thank you for any help.

    Hi Houcine,

    Seems like you've been having a little trouble getting your query posted - welcome (back?) to the e2e forum! From the title and body of your post, it sounds like you've might have tried a few things but are running into issues. Can you tell us what sort of problem you've been having? A 'simple' schematic is located in the AMC1304EVM User's Guide. As noted in the block diagram first page of the of the AMC1304M25 datasheet as well as in Figure 54, the shunt is normally referenced to AGND. If you exceed the common mode input voltage limits, you can run into some trouble with the bit stream output going into saturation.
