ADM6713 Absolute Maximum Ratings Question
ADI Technical Support, I have a question about absolute maximum ratings (AMR) published on the ADM6713 datasheet. If you review the section that lists the AMR, an ambient temperature of 25C is listed....

Part 1:Assuming the 739x is on layer 1 and layer 2 is a solid ground plane, then the termination resistor should be on layer 1. Part 2:digital traces need to referenced to ground planes and kept away...
View ArticleRe: AD9361 : RX and TX using the same LO
Rx and Tx LO frequencies are generated by dedicated RFPLLs. One for Tx and one for Rx. They can be set to the same or two different frequencies. BBPLL is common to both and is used to create all...

I'm finally now up to date with both the ADI "linux" and "hdl" (with pcore v8) repos. I did add "adi,tdd-use-fdd-vco-tables-enable" to my devictree, but I still had to make the following changes to...
View ArticleRe: AD8237 Gain/Bandwidth problem
Hey Achim thanks for the reply! I'm actually just trying to design a circuit for 0-3.3V sensors so I don't really need a negative Vs- thats why I just set it to ground. The issue in my lab is that my...

Re: AD8237 Gain/Bandwidth problem
Hello, you have an AC-coupled signal path. No matter what you apply to J17, the series capacitor will always block the DC-portion of your input signal. So the + input of the AD8237 (pin 2) will always...
