SM73201: RD-195

Part Number: SM73201

Hi! I was looking for more information on the RD-195. I watched the training video about Arc Detection: https://training.ti.com/rd-195-arc-detect-reference-solution, and was interested in understanding how to obtain the graph that is shown ("The Spectrum of Arcing System vs. Non-Arcing System") when using the device in my own arc testing set-up. 

Furthermore, I wanted to buy this product but am unable to find it anywhere, and am looking for suggestions as to any TI products that complete the same goal. 

Thank you!

    Hello,

    While the SM73201 is still an active product and will remain so, the RD-195 reference design was no longer manufacturable as of a few years ago so it was taken from the web.  Furthermore, most of the expertise on the arc-detection information are no longer available but the graph you're referring to is a power vs. frequency graph which indicates an FFT was performed on the incoming ADC data which produced the different energy content during an arcing vs. non-arcing condition.  The arc case looks to inject a lot of broad energy content in the 20-80kHz range.
