AFE4960EVM: AFE4960 EVM reception Issue

Part Number: AFE4960EVM
Other Parts Discussed in Thread: AFE4960

Hi team,

 

We are developing a medical ECG device which uses the AFE4960 as the ECG module. We can successfully communicate with the bio sensing GUO application and export the data.

But we are facing some issues,

1)How to convert the ADC RAW value to the ADC voltage? Could you please provide some examples to do the same?

2)Its the value "16771794" we are receiving when the simulator is not connected? There are so much noise in the output ,how to rectify it? When no simulator is connected why are we receiving the ADC voltage around -0.003134537mv ?

3)Attaching the AFE data At 1000Hz data rate with simulator and without simulator. Could you please check that its correct?

4)In the global settings, there is data rate option, Is the data rate same as the ADC sampling rate?

5)Also when we reduce  the data rate to 250Hz,the data is getting corrupted.
