Hi Guys,
I have a INA999 with a gain of 100 and Rsense is 2mOhm, trying to work out the output current, Vref is 1.25V.
I have tried this Vout = 1.25+100 * (Rsense * I) - however measuring Vout the current is incorrect.
Using the voltage drop across the sense resistor I can get better readings but want to get output from the op amp as it its going to the ADC so should be more accurate.
any thoughts?
