Part Number: ADS131E08
Hi Team,
I got a question from my customer with regards to the ADS131E0x family. Below is their question:
We understand from the calculation, the least possible ADC input voltage that ADC can convert for the configuration of 24 bit mode, voltage reference is +/-2.5V (to provide full scale of 5V) will be around 0.2uV..
Which means if the input step voltage is X*0.2uV the ADC conversion step is Y*1 bits.
The question is, Do you have any reference data from your experience what is the best ‘practical’ voltage step is a wise consideration to ensure the signal is well above the SNR and ADC conversion is absolute. Here practical means to overcome uncertain system noise like thermal, aperture, external factors etc. Of course this ‘practical’ step will impact the overall system accuracy, let’s keep it out for time being.
Is it like voltage in step of ‘500uV or 1mV’ or any ‘lesser’ you would prefer from your field experiences?.
Any way it shall be tested, but prior to that we need this data for simulation analysis.
THanks!
Best Regards,
Alfred
