Hi, guys, I have a question about the interface between sensor and ADC.
I have a power detector that produces voltage levels ranging from 0.26V to 1.1V.
My selected ADC input voltage range is 0-3.3V.
My question is that is that really necessary to build a interface using op-amp to map 0.26V to 0V and 1.1V to 3.3V accordingly?
Since the range of ADC covers the output voltage of detector, so I am thinking, theoretically, there is no need to build an interface, which is a waste of time.
