R2R DAC explained | How does a digital to analogue converter works?

In this video we break down the R-2R DAC, one of the simplest and most widely used digital-to-analogue converter designs. You’ll learn how the R2R ladder works, why it converts binary values into precise analogue voltages, what MSB and LSB really do and how resistor ratios shape accuracy. You’ll learn: • How digital values become analogue voltages • Why the R-2R ladder uses two resistor values • The maths behind each output step If you’re into electronics, microcontrollers or embedded systems, this guide gives you the fundamentals you need.
