Accuracy of EFM32 1.25V internal reference

Does anyone know where I can find the accuracy of the EFM32WG 1.25V internal reference? I couldn't find any information in the datasheet.

I would also like to know this in case of Leopard Gecko and 2.5V reference (but I suppose that these are the same in all Geckos). Supporter guys, can anyone help? Robot Happy  Thank you.

Re: Accuracy of EFM32 1.25V internal reference

For which peripheral? The ADC, DAC, and ACMP have separate references. I think, the the case of the ADC and DAC, you can determine the accuracy indirectly through the other specs. For the ACMP, I've found out recently that the reference isn't characterized, but we will be doing characterization on it in the near future.
