Forum Post: RE: ADS125H02EVM: Communication problem
Hi Adrian, The ADC and DMM may each have their own offsets and gain errors which combined add up to 0.75 mV difference. I don't see any issues there. 1) The offset calibration measurement is good....

Hi Mark, 1/ As you can see in figure 12, the two integrators of each input work one after the other, in ping-pong. These are 2 consecutive samples of the same channel. Hence the output samples come one...

Hi Martin, I'm sorry you are feeling grouchy. The ADS1232REF is not obsolete. I think that there is a misunderstanding as to the use of the ADS1232REF . It is not a development system. It is a method...

No problem. The full scale is set by the range you pick. No need to care about what is going on inside the device (what is the feedback cap or the reference the ADC uses...). It is "transparent" to the...

Hi Yi, Our system engineer suggests: ====== If they indeed need to separate the GND, they can treat ADC CLK as digital GND. ====== Thank you! Have a nice day! Best regards, Chen
View ArticleForum Post: RE: ADS131E08: Relation of input range vs. AVDD
Shota-san, That is correct. If VREFP=2.5V and VREFN=-2.5V, the VREF=2.5-(-2.5V)=5V and the full scale range of the ADC is ±5V. Also if the customer uses a pseudo-differential input (such as AINN=0V,...

Hi Brian, Thank you for your post. The commands you're sending to the ADS9224R look correct for reading and writing registers. There seems to be a slight delay between the SCLK falling edges and the...
