Jim, If this is the case, do you have any other hypotheses on why their part is behaving the way it is? Obviously the 4x interleaving setting is not the issue. Thanks, Brian

Hello Ibtesam, Thanks for your post! Low pass filter's (LPF's) are recommended to remove the high frequency signals that alias back into the sample band and patient protection is required by most (if...
View ArticleForum Post: RE: DAC161P997: Error reporting issues
Hi Sharada, If all of the error reporting is disabled do you still see this drop to ~1/2 of the setpoint? If so, this is likely a symbol timing issue which may cause the incorrect data being latched...

Hi Morita, Can you also clarify the meaning of 'Bad' from the original post as well as 'leads to error'? Is the conversion data erroneous or is it just the short DRDY signal?
View ArticleForum Post: RE: ADS1292: ADS1292R - Read Chip ID (0x00) register
Hi Kaloliya, Before trying to read the registers, are you sending the SDATAC command? I do not see it in your code. Are you using the correct SPI settings? You should be using CPOL = 0 and CPHA = 1.
