aduc847 ADC filtering

Question asked by Ascell on May 17, 2011

Hello all!:

 

I'm working with an aduc847 and the eval board.

 

I'm reading the signal from a load cell (from -200uV to 20020uV) and I have a problem with the data readed.

 

For example, with a little dead load in the cell I have this measurements:

 

8502984
8501899
8502025
8503006
8502469
8501334
8501443
8500833
8501512
8502104
8501317
8502138
8501970

 

I have a lot of variations. If I use only the stable value (for example 850 or 8501 in this case) the amount of points between the capacity and the zero is not enough for my application.

 

I need a 60.000 divisions estable value, so for this I need more or less 10 points/division....

 

How I can filter the data readed?Somebody knows any software filter to obtain a (more or less) stable value from this data?

 

Any help is welcome!

 

Thanks in advance
