Voltage Reference is an electronic component or circuit that provides accurate and stable voltage output. It is the standard used to establish the reference voltage in many electronic systems. The voltage reference can be a standalone integrated circuit (IC) or it can be a component included in a larger system. The output voltage of the voltage reference is usually very stable and is not affected by factors such as temperature changes, power supply voltage fluctuations, etc., which makes it an indispensable component in electronic design.
Application
Voltage Reference has a wide range of applications, covering almost all electronic devices and systems that require high-precision voltage reference. In the field of industrial automation, voltage reference is used in precision measuring instruments and sensor signal processing in process control systems to ensure the accuracy of measurement data and the stability of control processes. In the field of communication, as a reference voltage source for key components such as clock generator and signal modulator, it is very important to ensure the quality of communication. In the field of consumer electronics, with the popularity of smart devices, the demand for power management is increasing, and voltage reference plays an important role in battery management systems and charge control.

FAQ about PMIC - Voltage Reference
-
1. What is the reference voltage of the ADC?
The reference voltage of the ADC can be the MCU power supply voltage or the stable voltage provided inside the chip.
When the MCU power supply voltage is used as the reference voltage, the reference voltage of the ADC module is the MCU power supply voltage. For example, if the MCU power supply voltage is 5V, then the reference voltage of the ADC is 5V; if the power supply voltage is 3.3V, then the reference voltage of the ADC is 3.3V12. The advantage of this method is that it is simple and easy to implement, but the disadvantage is that the stability of the power supply voltage will affect the measurement accuracy of the ADC. If the power supply voltage is unstable, the reference voltage of the ADC will also change, resulting in inaccurate measurement results.

2. How to choose a voltage reference?
Voltage references are used in the following situations:
As a reference for measurement: When measuring voltage, the voltage reference provides a stable reference point, making the measurement result more accurate and reliable. When measuring, the negative end of the voltmeter is grounded and the positive end is connected to the measured point, so that the measured value is the voltage value of the measured point.
Adjust and calibrate other circuit elements: The reference voltage can be used to adjust and calibrate other circuit elements to improve the performance of the entire system. By comparing with the reference voltage, various parameters in the circuit can be accurately adjusted to ensure the stability and accuracy of the system.
Setting thresholds and judgments: In comparison circuits, reference voltages are used to set thresholds and make judgments. By comparing with the reference voltage, the rationality of various states and signals in the circuit can be determined.

3. What is a shunt voltage reference IC?
A shunt voltage reference IC is a chip used to measure the potential of each point in a circuit, mainly used to determine the reference potential of the circuit. It converts a DC power supply or battery-powered AC power into a low-voltage differential voltage signal output through a resistor, and then converts it into a digital quantity by an AD conversion circuit. It is widely used in various measuring instruments, meters and control systems.
