ADS131M02: Is there a filter design tool

Part Number: ADS131M02
Other Parts Discussed in Thread: ADS124S08

Hi 

Is there a filter design tool like this one for ADS131M02 

https://www.ti.com/tool/ADS124S08-EXCEL-CALC-TOOL 

  • Hello PYTsai,

    Unfortunately, I don't know of any design calculators for the ADS131Mx series like the ADS124S08 you've linked.

    With that being said, I wouldn't really say the ADS124S08 calculator is a "filter design" tool. It simply takes register settings, and other user configurations, like data rate, and plots what the response will look like for the digital filter. 

    Between the figures in the 8.3.7.2 Digital Filter Characteristic (which is normalized for which frequency you use, so you can do the substitution based on your OSR) and Table 8-3 Digital Filter Startup Times After Power-Up or Resynchronization (which has a column for settling time), I'm not sure what else you need to know in context of the digital filter.

    Best,

    -Cole
