Re: ADT7461: Confirming how remote temperature is represented
Ok, so I found Table 10 in the manual which describes how offsets are calculated using the two bytes. That seems to corroborate my understanding described above. So you can either look at it as one...

Hi all,I've been working on porting a project for the BF561 with a custom LDF from VDSP++ to CCES. Since the import tool was not much help here, I ended up creating a new project and adding the...

Thanks for you suggestion. The following is what I get which I set the TX2 1MHz offset from LO, while TX1 is set maximum attenuation. Even more and worse spurs. LO is about -56dBc. where the max spur...

There is nothing to say that you can not low pass filter on a differential signal. However, if you just need a single-ended signal, there is nothing wrong with using one output of the AD8333 and leave...

Can I use the FPGA board for EVAL-AD-FMCOMMS2-EBZ with EVAL-AD-FMCOMMS3-EBZ? They seems has the same interface.
View ArticleRe: AD831 getting hot
Yeah, this is normal for the AD831. It has a supply current of 100 mA nominal on a 9V supply, this is almost 1Watt of power it must dissipate from the PLCC package, which has no ground paddle to act...

Thanks John. I understand that I need to use an external ADC, but it seems the only input blocks available in the software are for audio inputs. How can I set up an input to function as a control in...
