Afternoon people, I'm new to electronics and have a question about voltage reference. What is it and how is it used?
Thanks for any help.
Thanks for any help.
An ADC, by definition, measures voltage. The ADC needs to know what a volt is. The voltage reference tells the ADC exactly what a volt is so the input to be measured can be compared to the standard.I understand the concept but what does adc use the reference for?
The ADC converts an analog voltage to a digital word representing that voltage, by comparing the analog voltage to the reference voltage.I understand the concept but what does adc use the reference for?
It teaches us to name the application so we don't get nebulous answers to a nebulous question and end up with nothing useful.I understand the concept but what does adc use the reference for?
The basis of operation of nearly all A/D converters is that they are ratiometric; that is, they generate an answer (i.e., the digital conversion result) in the form of a binary fraction between 0 and 1 equal to the input voltage divided by the reference voltage. The more accurate the reference voltage is, the more accurate the conversion result will be.I understand the concept but what does adc use the reference for?
Anywhere you need a predictable and stable voltage. Voltage regulators for instance. You needto compare an unpredictable voltage to a known voltage.Afternoon people, I'm new to electronics and have a question about voltage reference. What is it and how is it used?
