ELECTRICAL CHARACTERISTICS (continued)
(V
wise noted.)
Note 1: Guaranteed by design and characterization.
Note 2: Peak operating current measured during conversion. See Figure 4.
Note 3: Guaranteed by design, not production tested.
Note 4: A master device must provide a hold time of at least 300ns for the SDA signal in order to bridge the undefined region of
