I have a 0-5V sensor output that goes to an op amp buffer and then to an A/D. I only need data from 1-3.3V from the sensor output. Chopping the top end is easy by using a zener clamp or something similar. How do I remove the bottom end, so I don't see 0-1V data. I figure use an op amp, but what configuration?
