Re: 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...
View ArticleRe: 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...

Yess!! It looks like you called it. I added the bias to pin 2 and the wave form looks good at 20kHz. The gain is set to 6 and I'm running the same 100mV 20kHz wave through. So I think this design...

Re: AD8237 Gain/Bandwidth problem
Ok cool. I checked it out. How should I read the operating range? My configuration would be the 8237 with V+=3.3V and V-=0V. It gives me an operating voltage level from 1 to -1 common mode. My...

Where is the create button? It sounds dumb but I can't find it on here. It may be easier for you to PM to start it and I can reply with a pdf.

I don't know of any ADI DSPs with LVDS inputs. Certainly none of the SHARCs have this feature. We use LVDS routinely with SPORTs. You will probably need a Quad Receiver. There are several choices. The...
