ELECTRICAL CHARACTERISTICS: 2-WIRE INTERFACE
(2.5V ≤ V
Note 1: All voltages are referenced to V
Note 2: Offset specified after autocalibration cycle and Current Offset Bias Register = 00h.
Note 3: The DS2786B enters the sleep mode 1.5s to 2.2s after (SCL < V
Note 4: Timing must be fast enough to prevent the DS2786B from entering sleep mode due to bus low for period > t
Note 5: f
