(1)

Calculated using Pulse Count to Temperature LUT and 0.0625°C resolution per pulse, see Electrical Characteristics - Pulse Count to

Temperature LUT section.

(2)

Error can be linearly interpolated between temperatures given in table as shown in the Accuracy vs Temperature curves in Typical

Characteristics section.

(3)

Limit is using end point calculation.

6.5 Electrical Characteristics

Over operating free-air temperature range and operating VP-VN range (unless otherwise noted).
