Other Parts Discussed in Thread: ADS6125
Dear Technical Support Team,
I have three questions about ADS61B49. See attached file.
Q1)
Could you show the region of AVDD/AGND and DRVDD/DGND for each pins?
If I have missunderstanding, could you fix it correct?
I refer to the PCB and schematic of ADS6125EVM below.
Q2)
Should SEN pin of ADS61B49 connect AGND(Analog Ground)?
I found slightly difference of ground between ADS61B49 and ADS6125.
SEN pin of ADS61B49 is used with AVDD(Analog Power)
The one of ADS6125EVM is used with DRVDD(Digital Power)
Q3)
ADS61xxEVM have single point earth between AGND and DRGND.
Should ADS61B49 set single point earth between AGND and DRGND?
Best Regards,
