Specifications guaranteed for the stated global conditions. The device also meets the parameters specified when 0 < V IN1
< +6.5V, and at least one of V IN3 through V IN6 is between +2.7V and +5.5V, while the remaining V IN3 through V IN6 are
between 0 and +5.5V.
Device may be supplied from any one of IN_, except IN2.
The internal supply voltage, measured at ABP, equals the maximum of IN3 to IN6 if V IN1 = 0, or equals +5.4V if V IN1 >
+6.5V. For +4V < V IN1 < +6.5V and V IN3 through V IN6 > +2.7V, the input that powers the device cannot be determined.
100% production tested at T A = +25 ° C and T A = +125 ° C. Specifications at T A = -40 ° C are guaranteed by design.
V IN_ > 0.3 x ADC range.
Does not include the inaccuracy of the external +1.25V voltage reference.
DNL implicitly guaranteed by design in a sigma-delta converter.
C BUS = total capacitance of one bus line in pF. Rise and fall times are measured between 0.1 x V BUS and 0.9 x V BUS .
Input filters on SDA, SCL, A0, and A1 suppress noise spikes < 50ns.
Note 10: An additional cycle is required when writing to configuration memory for the first time.
