POWER REQUIREMENTS VDD 5.5 5.5 V max For specified performance 2.7 2.7 V min IDD Logic inputs = 0 V or VDD Normal Operation 600 600 μA max Power-Down 1.5 1.5 μA max 0.7 µA typically Auto Power-Down Mode VDD = 3 V; see the Operating Modes section 10 SPS Throughput Rate 6 6 μW typ 1 kSPS Throughput Rate 60 60 μW typ 10 kSPS Throughput Rate 600 600 μW typ Power-Down 3 3 μW max Typically 0.15 μW 1 B Version applies to AD7417 only with temperature range of −40°C to +85°C. A Version temperature range is −40°C to +125°C. For VDD = 2.7 V, TA = 85°C maximum and temperature sensor measurement error = ±3°C maximum. 2 See the Terminology section. 3 Refers to the input current when the part is not converting. Primarily due to reverse leakage current in the ESD protection diodes. 4 Sample tested during initial release and after any redesign or process change that may affect this parameter. 5 On-chip reference shuts down when an external reference is applied. 6 The accuracy of the temperature sensor is affected by reference tolerance.
