I'm going to use MCP4725 DAC to set voltage/current in a digital lab PSU, when I set the output of the DAC to 0 in Arduino there's a 23mV on DAC output and it's almost linear. I need to trim this offset error or at least reduce it to 1-2mV.
I did googled a bit and find this op amp configuration:
But it's not removing any offset from the output, any idea how can I remove this damned 23mV or at least reduce it to 2mV?
