High-Precision Low-Drift 5V Voltage Reference Circuit for ADC and Instrument Calibration

To design a precise voltage reference circuit with low drift for applications such as ADC (Analog-to-Digital Converter) calibration or instrument calibration, you can consider using a voltage reference IC or building a precision voltage reference circuit using discrete components. Here's a general approach to designing such a circuit
Components Required:
Voltage reference IC or precision operational amplifier (op-amp)
Precision resistors
Capacitors
Voltage regulator

I have learned absolutely nothing looking at this video. What is the purpose of it?

Hi pctuterman1! This video shows how a Voltage source must be unchanged over time. Here you see about 3 hours shrinking 1.29 minutes. Thank you for your comment.
