(1) Calculated using Pulse Count to Temperature LUT and 0.0625°C resolution per pulse, see sectionElectrical Characteristics - TO-92/LPG Pulse Count to Temperature LUT and Electrical Characteristics - WSON/DQX Pulse Count to Temperature LUT.
(2) Error can be linearly interpolated between temperatures given in table as shown in the Accuracy vs Temperature curves in sectionTypical Characteristics.
(3) Limit is using end point calculation.
