Hi Trailokya,
Thank you for your comment. BTW, when will the REF70 VSSOP package be shown in TI.com product folder? I couldn't find the part number for the VSSOP package.

Part Number: REF70 The datasheet recommends using a film capacitor for the output capacitor with a value between 1uF and 100uF, but is there an alternative that is almost as good but smaller? I read in a TI journal that it is also possible to use COG…

Hi Dennis
The output is oscillating. Can you please confirm it on the scope.
You are exxeding the output capacitor spec (57pf) and overall ESR. Can you please remove R29 and C37 and check the output.
Please refer the layout recommendation given at page…
Hello Sudhir,
Please take a look at our high precision REF70 family. This should provide higher initial accuracy, and better tempo and long term drift. Hope that helps.

Thanks.
Hi Himanshu,
I wouldn't recommend looking at each individual component, I would look at each individual signal chain. As such you will need to calibrate each channel of the ADS131M04 to ensure highest accuracy.
I recommend taking a look at the REF70…
Hi Kai,
Please let me know how to convert ppm / SQRT(Hz) to V / SQRT(Hz)?
I want to redesign the circuit using REF70 of TI or voltage reference from other companies.
Thank you.
