Sorry, this is not a convincing answer 🙁

Hi, I'd like an answer to my last comment.

The USB-TC-AI is not offered in the Digilent website, although it appears in the Series Datasheet. On the other hand, the USB-TEMP and USB-TEMP-AI present an identical Functional Block Diagram in Fig. 1 of the manual, with respect to the temperature measurements. The temperature measurement descriptions are also identical in the manual. The only difference is that the USB-TEMP-AI model substitute 4 temperature channels of the USB-TEMP model by 4 analog input voltage channels. So, I would expect the same performance about the temperature measurements. You can find significant differences not just for the thermocouple but also for RTD and NTC specs

I can see significant differences in the temperature specifications of these two models, with the USB-TEMP-AI module being worse. Since they sare the same measurement principles, it seems they should look the same. Regards, Manel USB_TEMP_TC_series_data.pdf
