I'm building a device to acquire current data through an appliance. The schematic can be seen below:
The problem is that I need this measurement to be step up tenfold, but I added a 2.5V reference just to make sure that the measurement stays within the 0V-5V range.
If I just use a gain op-amp, then the offset is also going to be step up tenfold, and the new offset would be 25V right?
How can I fix this?

Do you mean something like this?
