Are there any concerns about using an opamp as a comparator?
- When used as a comparator the propagation delay time becomes longer vs a comparator due to the charge/discharge of the internal phase compensation capacitor. Please conduct a thorough evaluation of the application.
  Especially with low current consumption types, in addition to the propagation delay time becoming larger there may be problems such as output malfunctions due to power supply noise, making them unsuitable for use as a comparator.
