How to detect the rising and falling edges during AD conversion? I want the light to be on when the voltage rises and off when it falls. The voltage range is 1.2V~2.0V. Do I compare the data collected...
Because the op amp is powered by a single power supply, a bias voltage VCM1 of tens of mV must be added (why?). I see that the classic differential amplifier circuits are all grounded? Also, I used a ...
