I have two signals (1-5 VDC) that I need to connect to a 16-bit analog to digital converter. The signals are fairly stable (temperature and pressure) so frequency response is not an issue. The problem that I am having is that the devices that I am finding for a 16-bit ADC have differential inputs (+/- 2.048V) and I have a single ended signal. How do I convert the single-ended signal to a differential. I was thinking of running the signal through a voltage divider and then taking the reduced signal to 1) an inverting OPA and 2) a non-inverting OPA to get the differential signal. Will this work?? Anything else I need to watch out for??
Thanks!
