  L DESIGN FEATURES How to Choose a Voltage Reference
  by Brendan Whelan Why Voltage References? 5V It is an analog world. All electronic
  devices must in some way interact with
  the “real” world, whether they are in
  an automobile, microwave oven or cell
  phone. To do that, electronics must be
  able to map real world measurements
  (speed, pressure, length, temperature)
  to a measurable quantity in the electronics world (voltage). Of course, to
  measure voltage, you need a standard
  to measure against. That standard is
  a voltage reference. The question for
  any system designer is not whether he
  needs a voltage reference, but rather,
  which one?
  A voltage reference is simply that—a
  circuit or circuit element that provides
  a known potential for as long as the circuit requires it. This may be minutes,
  hours or years. If a product requires
  information about the world, such VIN 18k LTC1286
