(1) Parameters are characterized up to T_A = 105°C unless otherwise noted.
(2) Calculated using the box method: (MAX(-40°C to 85°C) - MIN(-40°C to 85°C)) / MIN(-40°C to 85°C) / (85°C - (-40°C))
(3) Calculated using the ADC output code and the box method:
(MAX-code(2.5 V to 3.6 V) - MIN-code(2.5 V to 3.6 V)) / MIN-code(2.5 V to 3.6 V) / (3.6 V - 2.5 V)
