I have a 12V (single ended) power supply available for an op amp circuit I am designing. I want it to be very precise around zero volts for an output. I already thought of using a virtual ground, but I am putting the output into a Max 10 FPGA, so I do not think that I can accommodate that.
Is it possible to use a second op-amp and make the Vcc of it ground and the Vee of it as 12V and use it as an inverting op-amp, to then use that as the power supply for the first op-amp?
The op amps that I have are LM358, but I do not think that it makes a difference for this scenario. I am shifting the input and scaling it with a circuit like the one below, I am just trying to improve its resolution at small outputs.
