Is it possible to compare input bipolar signal directly with Ground level, using AD8611 comparator under unipolar power supply?
The sinusoidal signal up to 1V amplitude is present on Input.
Or V- pin of the AD8611 must be connected to negative power source in this case?
Preferably minimal components number should be used and unipolar power. So positive Vref source and RC circuit, so as bipolar supply, are undesirable
