How to Design 24VAC to DC Power Supply for HVAC Applications Part 2

In the video we look at how to design a 24VAC power supply for industrial and HVAC applications. The supply will be flexible enough to handle DC voltage inputs. The power supply will employ a DC to DC buck converter, half wave rectifier, input protection against over voltage, and output noise reduction circuit features. In part 2 we look at the PCB design, the finished product, and capture some test data to see how it is working.

Ways to Improve ADC Measurement Accuracy and Resolution Part 2

In part two of this 4 or 5 part series, we look at how the Successive Approximation or SAR ADC architecture works and understand its limitations. Note SAR based ADC architecture is what you typically find in microcontrollers.
