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. In addition, in the field of medical electronics, aerospace, scientific research and other high-precision requirements.
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. 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.

3. What is a reference voltage IC?
A reference voltage IC is a voltage reference IC. A voltage reference IC is a precise, temperature-compensated voltage source that can provide a specific output voltage value, such as 1.225V, 4.096V or 10.000V. They are mainly used to provide a stable and precise voltage reference in various electronic systems to ensure the stability and reliability of the system.
There are two main types of voltage reference ICs: shunt voltage reference ICs and series voltage reference ICs. The shunt voltage reference IC uses an external series resistor to set the maximum current supplied to the load. It is suitable for situations where the load is almost constant and the power supply changes very little. The series voltage reference IC contains a voltage reference and an amplifier that controls the output voltage. It is suitable for situations where the load current is variable and the output voltage changes strictly when the temperature changes.
