Lecture 24 - ADC/DAC

Date: 11/10/16

Summary

We have already talked about the digital representation of voltage and even used an analog-to-digital converter to measure voltages with the Arduino. In this class we’re going to dive into how analog-to-digital converters work and the advantages of different converter architectures. We will also introduce digital-to-analog conversion – generating a voltage from a digital representation.
