WebLet's first suppose, with regard to the op-amp comparator circuit above, that VIN is lower than the DC voltage level at VREF, or (VIN VREF). The output of the comparator will be LOW and at the negative supply voltage, -Vcc, causing a negative saturation of the output since the non-inverting (positive) input is less than the inverting (negative) input. WebAlthough general purpose op-amps (like the TL071) can be used as comparators, ##### specially designed op-amps (like the LM311) can switch faster and have additional features not found on general-purpose ##### op-amps. For non-critical applications, general purpose op-amps are satisfactory and will be used in this lab. Comparator
