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. When to use voltage reference?
The voltage reference is used in the following situations:
As a basis 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.
Definition and function of voltage reference:
Voltage reference refers to the voltage value used as a reference in an electronic circuit. It can be constant or variable, but usually requires high precision, low noise and stability. The reference voltage is implemented through specialized integrated circuits, resistor networks, voltage regulators, and temperature compensation circuits to ensure that the voltage value in the circuit always remains within the set range, thereby ensuring the stability and accuracy of the system.
