For a hobby project that I am doing, I would like to measure the voltage across a shunt resistor with a differential ADC. I am thinking to use the ADS1292 of TI.
However, I have the following question. Since I also expect a negative voltage across the shunt resistor. I would like to generate a bipolar reference Voltage for the ADC
How can I best accomplish that? I have a 4.5V power supply and want to use a rail splitter. Is that stable enough for a precision measurement? If there is a better way of doing that I am open to suggestions.
