I need it to amplify the voltage drop over a sense resistor.
If the sense resistor is 0.1 ohms and i have a 100mA current through
it then the voltage across it will be something like 0.01V. I need the
opamp to amplify it 15 times and output 150mV.
I need its output to be as close as it can to GND, the +24V supply is
just a requirement for this circuit, the voltages will never reach
that value.
