FAQ about PMIC - Voltage Reference
-
1. What is a CMOS voltage reference?
CMOS voltage reference refers to a voltage standard used for digital circuit transmission. Its output voltage is lower than VSS+0.5V (VSS is digital ground) as logic 0, the output high level is about 0.9Vcc, and the output low level is about 0.1Vcc. The input voltage of the CMOS circuit is high when it is close to the power supply voltage and low when it is close to 0V. It has a wide noise margin and high input impedance.

2. 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.

3. What is a voltage reference IC?
A voltage reference IC is an integrated circuit used to provide a stable voltage reference point. It is widely used in various electronic circuits to ensure the normal operation of other circuits. Voltage reference ICs are key components for high-precision data acquisition and processing, and are often used in measuring instruments, control systems and other fields.
The working principle of a voltage reference IC is to convert a DC power supply or battery-powered AC power into a low-voltage differential voltage signal output by reducing the voltage through a resistor, and then convert it into a digital quantity by an analog-to-digital conversion circuit. Such devices play an important role in various measuring instruments, meters and control systems.
