ELECTRICAL CHARACTERISTICS (continued)
(V
Note 1: +25°C ≤ T
Note 2: If both the MAX6654 and the remote junction are below T
Note 3: The conversion time doubles for the extended resolution mode. This causes the average operating current to approximately
Note 4: The serial interface resets when SMBCLK is low for more than t
Note 5: Note that a transition must internally provide at least a hold time to bridge the undefined region (300ns max) of SMBCLK’s
