I want to use one of the inputs as the reference voltage and the other as Vin in a conventional comparator structure. Can it be used as an integrator if the reference voltage is higher than the Vin voltage?
As long as the reference voltage is higher than Vin, will the same result be obtained regardless of the reference voltage?
The output Voltage range will be poor and the drive strength as well, so these may compromise behavior. An ideal op amp has ideal(ish) output as well as input attributes.
