IDD (Power-Down Mode) 10 μA VDD = 3.3 V, VIH = VDD, and VIL = GND 10 μA VDD = 5 V, VIH = VDD, and VIL = GND Power Dissipation 10 mW VDD = 3.3 V, normal mode 33 μW VDD = 3.3 V, shutdown mode 1 See the Terminology section. 2 DC specifications are tested with the outputs unloaded. 3 Linearity is tested using a reduced code range: ADT7516 (Code 115 to 4095); ADT7517 (Code 28 to 1023); ADT7519 (Code 8 to 255). 4 Guaranteed by design and characterization, not production tested. 5 Round robin is the continuous sequential measurement of the following channels: VDD, internal temperature, external temperature (AIN1, AIN2), AIN3, and AIN4. 6 For the amplifier output to reach its minimum voltage, the offset error must be negative. For the amplifier output to reach its maximum voltage (VREF = VDD), the offset plus gain error must be positive. 7 The SDA and SCL timing is measured with the input filters turned on to meet the fast mode I2C specification. Switching off the input filters improves the transfer rate but has a negative effect on the EMC behavior of the part. 8 Guaranteed by design, not production tested. All I2C timing specifications are for fast mode operation but the interface is still capable of handling the slower standard rate specifications. 9 The interface is also capable of handling the I2C standard mode rise time specification of 1000 ns. 10 All input signals are specified with tr = tf = 5 ns (10% to 90% of VDD), and timed from a voltage level of 1.6 V. 11 Measured with the load circuit shown in Figure 4. 12 The IDD specification is valid for all DAC codes and full-scale analog input voltages. Interface inactive. All DACs and ADCs active. Load currents excluded.
