Voltage References The reference voltage source is an extremely important component of analog integrated circuits, which provides a reference voltage or a regulated power supply and an excitation source for series-type voltage regulator circuits, A/D and D/A converters, or sensors. In addition, the reference voltage source can also be used as a standard battery, the calibration standard of the instrument head and constitute a precision current source.
