Voltage References

A voltage reference is a type of power management integrated circuit (IC) that provides a stable, fixed voltage output. Voltage references are used in a variety of electronic circuits, such as power supplies, data converters, and instrumentation amplifiers, to provide a stable reference against which other voltages can be measured or compared. Voltage references typically use a precision voltage reference diode, such as a Zener diode, to generate the reference voltage. The output of the voltage reference is typically buffered by an amplifier to provide a high-impedance output and improve the reference's accuracy and stability. Voltage references are essential for ensuring the accuracy and precision of many electronic circuits.
