Hello all,
I have a question which I was thinking of. Most sensors have some sort of gain stage to bring a small signal out of nosie. If a sensor is good deal from processor then a twisted pair is used to bring signal into the processor.
Has anyone built a circuit with sensor, gain stage, and discrete ADC on a circuit far from processor. Then the data and clock lines and power supply and ground would go out. I wonder if the component has a high rated PSRR if this would be a worthwhile approach.
