The typical optocoupler concerns regarding uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects are eliminated with the simple iCoupler digital interfaces and stable performance characteristics. The need for external drivers and other discrete components is eliminated with these iCoupler products. Furthermore, iCoupler devices consume one-tenth to one-sixth the power of optocouplers at comparable signal data rates. The ADuM120x isolators provide two independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide). Both parts operate with the supply voltage on either side ranging from 2.7 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling a voltage translation functionality across the isolation barrier. In addition, the ADuM120x provide low pulse width distortion (<3 ns for CR grade) and tight channel-to-channel matching (<3 ns for CR grade). Unlike other optocoupler alternatives, the ADuM120x isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and during power-up/power-down conditions. ADuM1200W and ADuM1201W are automotive grade versions qualified for 125C operation per AEC-Q100. See the Automotive Products section for more details.

Opposing directional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on opposing sides of the isolation barrier. 7 CMH is the maximum common-mode voltage slew rate that can be sustained while maintaining VO > 0.8 VDD2. CML is the maximum common-mode voltage slew rate that can be sustained while maintaining VO < 0.8 V. The common-mode voltage slew rates apply to both rising and falling common-mode voltage edges. The transient magnitude is the range over which the common mode is slewed. 8 Dynamic supply current is the incremental amount of supply current required for a 1 Mbps increase in the signal data rate.

H | Page 23 of 28 ADuM1200/ADuM1201 APPLICATIONS INFORMATION PCB LAYOUT The pulses at the transformer output have an amplitude greater than 1.0 V. The decoder has a sensing threshold at about 0.5 V, therefore establishing a 0.5 V margin in which induced voltages can be tolerated. The voltage induced across the receiving coil is given by The ADuM120x digital isolators require no external interface circuitry for the logic interfaces. Power supply bypassing is strongly recommended at the input and output supply pins. The capacitor value should be between 0.01 F and 0.1 F. The total lead length between both ends of the capacitor and the input power supply pin should not exceed 20 mm. V = (-d/dt)rn2; n = 1, 2, ... , N PROPAGATION DELAY-RELATED PARAMETERS Propagation delay is a parameter that describes the time it takes a logic signal to propagate through a component. The propagation delay to a Logic low output can differ from the propagation delay to a Logic high output. 50% 100 50% Figure 12. Propagation Delay Parameters Pulse width distortion is the maximum difference between these two propagation delay values and is an indication of how accurately the timing of the input signal is preserved. Channel-to-channel matching refers to the maximum amount that the propagation delay differs between channels within a single ADuM120x component. MAXIMUM ALLOWABLE MAGNETIC FLUX DENSITY (kgauss) OUTPUT (VOx) tPHL 04642-012 tPLH Given the geometry of the receiving coil in the ADuM120x and an imposed requirement that the induced voltage be 50% at most of the 0.5 V margin at the decoder, a maximum allowable magnetic field is calculated, as shown in Figure 13. 10 1 0.1 0.01 Propagation delay skew refers to the maximum amount that the propagation delay differs between multiple ADuM120x components operating under the same conditions. 0.001 1k 10k 1M 10M 100k MAGNETIC FIELD FREQUENCY (Hz) 100M 04642-013 INPUT (VIx) where: is the magnetic flux density (gauss). N is the number of turns in the receiving coil. rn is the radius of the nth turn in the receiving coil (cm). Figure 13. Maximum Allowable External Magnetic Flux Density DC CORRECTNESS AND MAGNETIC FIELD IMMUNITY Positive and negative logic transitions at the isolator input send narrow (~1 ns) pulses to the decoder via the transformer. The decoder is bistable and is therefore either set or reset by the pulses, indicating input logic transitions. In the absence of logic transitions of more than ~1 s at the input, a periodic set of refresh pulses indicative of the correct input state is sent to ensure dc correctness at the output. If the decoder receives no internal pulses for more than about 5 s, the input side is assumed to be unpowered or nonfunctional, in which case the isolator output is forced to a default state (see Table 17 and Table 18) by the watchdog timer circuit. The ADuM120x are extremely immune to external magnetic fields. The limitation on the magnetic field immunity of the ADuM120x is set by the condition in which induced voltage in the receiving coil of the transformer is sufficiently large enough to either falsely set or reset the decoder. The following analysis defines the conditions under which this can occur. The 3 V operating condition of the ADuM120x is examined because it represents the most susceptible mode of operation. 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 occurs during a transmitted pulse (and has the worst-case polarity), it reduces 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 away from the ADuM120x transformers. Figure 14 expresses these allowable current magnitudes as a function of frequency for selected distances. As seen, the ADuM120x are extremely immune and can be affected only by extremely large currents operating very close to the component at a high frequency. For the 1 MHz example, a 0.5 kA current would have to be placed 5 mm away from the ADuM120x to affect the operation of the component. Rev.

DISTANCE = 1m 100 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 ADuM120x. 10 DISTANCE = 100mm 1 DISTANCE = 5mm 0.1 0.01 1k 10k 100k 1M 10M 100M MAGNETIC FIELD FREQUENCY (Hz) 04642-014 MAXIMUM ALLOWABLE CURRENT (kA) 1000 Figure 14. Maximum Allowable Current for Various Current-to-ADuM120x Spacings Note that, at combinations of strong magnetic fields and high frequencies, any loops formed by PCB traces can induce sufficiently large error voltages to trigger the threshold 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 ADuM120x 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 IDDI = IDDI (Q) f 0.5fr IDDI = IDDI (D) x (2f - fr) + IDDI (Q) f > 0.5fr For each output channel, the supply current is given by IDDO = IDDO (Q) 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 14 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 the 50-year service life voltage. Operation at these high working voltages can lead to shortened insulation life in some cases. The insulation lifetime of the ADuM120x depends on the voltage waveform type imposed across the isolation barrier. The iCoupler insulation structure degrades at different rates depending on whether the waveform is bipolar ac, unipolar ac, or dc. Figure 15, Figure 16, and Figure 17 illustrate these different isolation voltage waveforms, respectively. 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. f 0.5fr -3 IDDO = (IDDO (D) + (0.5 x 10 ) x CLVDDO) x (2f - fr) + IDDO (Q) f > 0.5fr where: IDDI (D), IDDO (D) are the input and output dynamic supply currents per channel (mA/Mbps). CL is the output load capacitance (pF). VDDO is the output supply voltage (V). f is the input logic signal frequency (MHz, half of the input data rate, NRZ signaling). fr is the input stage refresh rate (Mbps). IDDI (Q), IDDO (Q) are the specified input and output quiescent supply currents (mA). In the case of unipolar ac or dc voltage, the stress on the insulation is significantly lower, which allows operation at higher working voltages yet still achieves a 50-year service life. The working voltages listed in Table 14 can be applied while maintaining the 50-year minimum lifetime provided the voltage conforms to either the unipolar ac or dc voltage cases. Any cross insulation voltage waveform that does not conform to Figure 16 or Figure 17 is to be treated as a bipolar ac waveform, and its peak voltage is to be limited to the 50-year lifetime voltage value listed in Table 14. To calculate the total IDD1 and IDD2 supply currents, the supply currents for each input and output channel corresponding to IDD1 and IDD2 are calculated and totaled. Figure 6 and Figure 7 provide per-channel supply currents as a function of data rate for an unloaded output condition. Figure 8 provides perchannel supply current as a function of data rate for a 15 pF output condition. Figure 9 through Figure 11 provide total Rev.
