Note 1: 100% production tested at TA = +25°C and TA = +85°C. Specifications at TA = -40°C are guaranteed by design.
Note 2: Device may be supplied from IN1–IN4 or VCC.
Note 3: The internal supply voltage, measured at VCC, equals the maximum of IN1–IN4.
Note 4: VIN_ > 0.3 x ADC range.
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
Σ converter.
Note 7: CBUS = total capacitance of one bus line in picofarads. Rise and fall times are measured between 0.1 x VBUS and 0.9 x
VBUS.
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.
TIMING CHARACTERISTICS
(VIN1–VIN4 or VCC = 2.7V to 5.8V, AUXIN = WDI = GND, MARGIN = MR = DBP, TA = -40°C to +85°C, unless otherwise noted. Typical
values are at TIN1 = +25°C.) (Notes 1, 2, 3)
