(1)

Calculated using Pulse Count to Temperature LUT and 0.0625°C resolution per pulse, see section .

(2)

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

Typical Characteristics.

(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).
