adum1410/adum1411/adum1412 rev. h | page 20 of 24 for example, at a magnetic field frequency of 1 mhz, the maximum allowable magnetic field of 0.2 kgauss induces a voltage of 0.25 v at the receiving coil. this is about 50% of the sensing threshold and does not cause a faulty output transition. similarly, if such an event occurred during a transmitted pulse (and had the worst-case polarity), it would reduce the received pulse from >1.0 v to 0.75 v, still well above the 0.5 v sensing threshold of the decoder. the preceding magnetic flux density values correspond to specific current magnitudes at given distances from the adum141x transformers. figure 19 shows these allowable current magnitudes as a function of frequency for selected distances. as shown, the adum141x is extremely immune and can be affected only by extremely large currents operated at high frequency very close to the component. for the 1 mhz example noted previously, a 0.5 ka current would have to be placed 5 mm away from the adum141x to affect the operation of the component. magnetic field frequency (hz) maximum allowable current (ka) 1000 100 10 1 0.1 0.01 1k 10k 100m 100k 1m 10m distance = 5mm distance = 1m distance = 100mm 06580-019 figure 19. maximum allowable current for various current-to-adum141x spacings note that at combinations of strong magnetic field and high frequency, any loops formed by printed circuit board traces can induce error voltages sufficiently large enough to trigger the thresholds of succeeding circuitry. care should be taken in the layout of such traces to avoid this possibility. power consumption the supply current at a given channel of the adum141x isolator is a function of the supply voltage, the data rate of the channel, and the output load of the channel. for each input channel, the supply current is given by i ddi = i ddi ( q ) f 0.5 f r i ddi = i ddi (d) (2 f ? f r ) + i ddi ( q ) f > 0.5 f r for each output channel, the supply current is given by i ddo = i ddo ( q ) f 0.5 f r i ddo = ( i ddo ( d ) + (0.5 10 ?3 ) c l v ddo ) (2 f ? f r ) + i ddo ( q ) f > 0.5 f r where: i ddi (d) , i ddo (d) are the input and output dynamic supply currents per channel (ma/mbps). c l is the output load capacitance (pf). v ddo is the output supply voltage (v). f is the input logic signal frequency (mhz); it is half the input data rate, expressed in units of mbps. f r is the input stage refresh rate (mbps). i ddi (q) , i ddo (q) are the specified input and output quiescent supply currents (ma). to calculate the total v dd1 and v dd2 supply current, the supply currents for each input and output channel corresponding to v dd1 and v dd2 are calculated and totaled. figure 8 and figure 9 show per-channel supply currents as a function of data rate for an unloaded output condition. figure 10 shows the per-channel supply current as a function of data rate for a 15 pf output condition. figure 11 through figure 15 show the total v dd1 and v dd2 supply current as a function of data rate for adum1410/ adum1411/adum1412 channel configurations. insulation lifetime all insulation structures eventually break down when subjected to voltage stress over a sufficiently long period. the rate of insulation degradation is dependent on the characteristics of the voltage waveform applied across the insulation. in addition to the testing performed by the regulatory agencies, analog devices carries out an extensive set of evaluations to determine the lifetime of the insulation structure within the adum141x. analog devices performs accelerated life testing using voltage levels higher than the rated continuous working voltage. acceleration factors for several operating conditions are determined. these factors allow calculation of the time to failure at the actual working voltage. the values shown in table 10 summarize the peak voltage for 50 years of service life for a bipolar ac operating condition and the maximum csa/vde approved working voltages. in many cases, the approved working voltage is higher than 50-year service life voltage. operation at these high working voltages can lead to shortened insulation life in some cases.
adum1410/adum1411/adum1412 rev. h | page 21 of 24 the insulation lifetime of the adum141x depends on the voltage waveform type imposed across the isolation barrier. the i coupler insulation structure degrades at different rates depending on whether the waveform is bipolar ac, unipolar ac, or dc. figure 20 , figure 21 , and figure 22 illustrate these different isolation voltage waveforms. note that the voltage presented in figure 21 is shown as sinusoidal for illustration purposes only. it is meant to represent any voltage waveform varying between 0 v and some limiting value. the limiting value can be positive or negative, but the voltage cannot cross 0 v. bipolar ac voltage is the most stringent environment. the goal of a 50-year operating lifetime under the ac bipolar condition determines the analog devices recommended maximum working voltage. 0v rated peak voltage 06580-020 figure 20. bipolar ac waveform in the case of unipolar ac or dc voltage, the stress on the insulation is significantly lower. this allows operation at higher working voltages while still achieving a 50-year service life. the working voltages listed in table 10 can be applied while maintaining the 50-year minimum lifetime provided the voltage conforms to either the unipolar ac or dc voltage case. any cross- insulation voltage waveform that does not conform to figure 21 or figure 22 should be treated as a bipolar ac waveform, and its peak voltage should be limited to the 50-year lifetime voltage value listed in table 10 . 0v rated peak voltage 06580-021 figure 21. unipolar ac waveform 0v rated peak voltage 06580-022 figure 22. dc waveform
