I'm wondering about the best ways to convert my unipolar single ended sensor output to differential input of ADC. I don't need any signal amplification or just a mirrored signal and its original signal is enough.
I can think of two ways:
either to use a single op amp inverter with just 2 resistors.
I really don't know the advantage of these two dual op amp design in term of signal accuracy. I got a feeling that the first choice is better for me.
my parameters are signal accuracy, component number, PCB size, power consumption.
anyone has an idea?
