Hi Takumi-san, I'm still not able to get the exact 0.112% value, but I think the issue is that this section of the datasheet was written while the device was still in preview, and it looks like they updated some specs for the final released version of this part without going back to revise the example in this section. For example the paragraph at the beginning of section 9.2.2 says the TUE is 0.02% FSR typical, but the electrical characteristic table shows 0.04%FSR typical. When I use the 0.02% value I get 0.114%FSR which is closer to the value calculated in the example. Your calculation is correct assuming a 2.5V full scale range. My only comment would be to use the typical value for TUE. The typical value is given at 25°C, and the min/max value is given across the entire temperature range this device is characterized for (–40°C to +125°C). So in this example, since we are only concerned with the 0 to 100C range, you should use the typical spec and then the drift specs will add only the drift for the 0°C to 100°C range. The full-scale error and zero-scale errors are end point errors due to the internal output buffer not being able to output values at the power rails. Best, Katlynne Jones
