Grasp voltage-ref temp drift

Posted: 30 Oct 2012 ?? ?Print Version ?Bookmark and Share

Keywords:voltage reference? external factors? temperature?

A perfect voltage reference produces a stable voltage independent of any external factors. Real-world voltage references, of course, are subject to errors caused by many external factors. One cause of these major errors is temperature. Without care, it is easy to operate a voltage reference outside its operating temperature range. This application note describes how references respond to temperature changes, and how self-heating can cause a voltage reference to operate outside its recommended temperature range. Once understood, this knowledge can then be used to avoid making this design error.
