What is meant by voltage reference?

A voltage reference is an electronic device that ideally produces a fixed (constant) voltage irrespective of the loading on the device, power supply variations, temperature changes, and the passage of time.

What is the difference between a voltage converter and a voltage regulator?

Unlike a voltage converter, which seeks to actually alter the voltage amount, a voltage regulator is a piece of equipment that is: Used to maintain a constant level of voltage in a given circuit, regardless of changes to load conditions or input.

What is a voltage regulator called?

Many simple DC power supplies regulate the voltage using either series or shunt regulators, but most apply a voltage reference using a shunt regulator such as a Zener diode, avalanche breakdown diode, or voltage regulator tube.

How do I choose a voltage reference?

Choosing a Reference

1. Is the supply voltage very high?
2. Does the supply voltage or load current vary widely?
3. Require high power efficiency?
4. Figure your real-world temperature range.
5. Be realistic about required accuracy.
6. What is the real supply range?
7. How much power can the reference consume?
8. How much load current?

What does 5 volt reference mean?

In modern vehicle design, 5-volt reference signals/circuits are a key aspect of vehicle command and control. As summarized by Gary Goms, the 5-volt reference signal typically. “flows through a sensor containing a resistance that varies according to changes in temperature, pressure or position.

What is ADC voltage reference?

ADCs convert analog inputs that can vary from zero volts on up to a maximum voltage level that is called the reference voltage. The reference voltage determines the ceiling of what the ADC can convert, and is essentially the yardstick against which every proportion and result is measured.

Why VREF is used in ADC?

Voltage references (VREF) are beneficial and often necessary for high-accuracy signal chain applications. This is because a standard signal chain contains a data converter, such as the Analog-to-digital converter (ADC) or Digital-to-analog converter (DAC), which measure or create a precise signal.
