AD75019 driven by an Arduino

Dear All,

I am coming back to my previous discussion about the many problems I had trying to drive an AD75019 with an Ardunio.

Today, all those problems are solved. There were many causes, but defects in the power supply and in the connections were the main causes.

Today, I run the AD75019 on a board made by Dr. Yannick Verbelen and available at

This board provides all power from a standard USB connector as well as proper start up sequencing and connection points for all the analog inputs/outputs and for SPI.

I've made some videos showing the results:

I hope this information will help some future AD75019 users.

Again thanks to Stephen Nugent for all his patient help in working with me on this.
