TIMING CHARACTERISTICS
(V
values are at T
Note 1: 100% production tested at T
Note 2: Device may be supplied from IN1–IN4 or V
Note 3: The internal supply voltage, measured at V
Note 4: V
Note 5: Does not include the inaccuracy of the 1.25V input reference voltage (MAX6884 only).
Note 6: DNL is implicitly guaranteed by design in a
Note 7: C
Note 8: Input filters on SDA, SCL, and A0 suppress noise spikes <50ns.
Note 9: An additional cycle is required when writing to configuration memory for the first time.
