The ±2.5°C accuracy is the headline spec that decides whether this part clears the thermal budget. For a CPU or FPGA die monitor, that margin is tight enough to trigger a throttle or fan ramp without false alarms.
The accuracy is ±2.5°C over the -40°C to 125°C sensing range. That is the figure to use for thermal-budget calculations and fan-control thresholds.
