GENERAL DESCRIPTION
The ADuM440x 1 are 4-channel digital isolators based on the Analog Devices, Inc., iCoupler(R) technology. Combining high speed CMOS and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics that are superior to the alternatives, such as optocoupler devices and other integrated couplers. The ADuM440x isolators provide four independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide). All models 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. The ADuM440x isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and during power-up/power-down conditions. This family of isolators, like many Analog Devices isolators, offers very low power consumption, consuming one-tenth to one-sixth the power of comparable isolators at comparable data rates up to 10 Mbps. All models of the ADuM440x provide low pulse width distortion (<2 ns for C grade). In addition, every model has an input glitch filter to protect against extraneous noise disturbances. The ADuM440x contain circuit and layout enhancements to help achieve system-level IEC 61000-4-x compliance (ESD/burst/surge). The precise capability in these tests for the ADuM440x are strongly determined by the design and layout of the user's board or module. For more information, see the AN-793 Application Note, ESD/Latch-Up Considerations with iCoupler Isolation Products.

ADuM4400/ADuM4401/ADuM4402 APPLICATIONS INFORMATION
PC BOARD LAYOUT
The ADuM440x digital isolators require no external interface circuitry for the logic interfaces. Power supply bypassing is strongly recommended at the input and output supply pins (see Figure 17). Bypass capacitors are most conveniently connected between Pin 1 and Pin 2 for VDD1 and between Pin 15 and Pin 16 for VDD2. 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. Bypassing between Pin 1 and Pin 8 and between Pin 9 and Pin 16 should also be considered unless the ground pair on each package side are connected close to the package.

While the ADuM440x improve system-level ESD reliability, they are no substitute for a robust system-level design. See the AN-793 Application Note, ESD/Latch-Up Considerations with iCoupler Isolation Products, for detailed recommendations on board layout and system-level design.
PROPAGATION DELAY-RELATED PARAMETERS
Propagation delay is a parameter that describes the length of time for a logic signal to propagate through a component. The propagation delay to a logic low output can differ from the propagation delay to logic high.

Figure 17. Recommended Printed Circuit Board Layout
In applications involving high common-mode transients, ensure that board coupling across the isolation barrier is minimized. Furthermore, the board layout should be designed such that any coupling that does occur equally affects all pins on a given component side. Failure to ensure this could cause voltage differentials between pins exceeding the Absolute Maximum Ratings of the device, thereby leading to latch-up or permanent damage.
Pulse width distortion is the maximum difference between these two propagation delay values and is an indication of how accurately the input signal's timing is preserved. Channel-to-channel matching refers to the maximum amount the propagation delay differs among channels within a single ADuM440x component. Propagation delay skew refers to the maximum amount the propagation delay differs among multiple ADuM440x components operated under the same conditions.
SYSTEM-LEVEL ESD CONSIDERATIONS AND ENHANCEMENTS
System-level ESD reliability (for example, per IEC 61000-4-x) is highly dependent on system design, which varies widely by application. The ADuM440x incorporate many enhancements to make ESD reliability less dependent on system design. The enhancements include * ESD protection cells added to all input/output interfaces. * Key metal trace resistances reduced using wider geometry and paralleling of lines with vias. * The SCR effect, inherent in CMOS devices, minimized by using guarding and isolation techniques between PMOS and NMOS devices. * Areas of high electric field concentration eliminated using 45 corners on metal traces. * Supply pin overvoltage prevented with larger ESD clamps between each supply pin and its respective ground.
DC CORRECTNESS AND MAGNETIC FIELD IMMUNITY
Positive and negative logic transitions at the isolator input cause narrow (~1 ns) pulses to be sent via the transformer to the decoder. The decoder is bistable and is therefore either set or reset by the pulses, indicating input logic transitions. In the absence of logic transitions at the input for more than ~1 s, a periodic set of refresh pulses indicative of the correct input state are sent to ensure dc correctness at the output. If the decoder receives no internal pulses for more than approximately 5 s, the input side is assumed to be without power or nonfunctional; in which case, the isolator output is forced to a default state (see Table 20) by the watchdog timer circuit. The limitation on the ADuM440x magnetic field immunity is set by the condition in which induced voltage in the transformer's receiving coil is 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 ADuM440x is examined because it represents the most susceptible mode of operation.

ADuM4400/ADuM4401/ADuM4402
MAXIMUM ALLOWABLE CURRENT (kA)
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, thereby establishing a 0.5 V margin in which induced voltages can be tolerated. The voltage induced across the receiving coil is given by V = (-d/dt)rn2; n = 1, 2,..., N 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). Given the geometry of the receiving coil in the ADuM440x and an imposed requirement that the induced voltage be at most 50% of the 0.5 V margin at the decoder, a maximum allowable magnetic field is calculated as shown in Figure 19.

Note that at combinations of strong magnetic field and high frequency, any loops formed by printed circuit board traces may induce sufficiently large error voltages to trigger the thresholds of succeeding circuitry. Care should be taken in the layout of such traces to avoid this possibility.

Figure 19. Maximum Allowable External Magnetic Flux Density
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 were to occur during a transmitted pulse (and was of 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 away from the ADuM440x transformers. Figure 20 expresses these allowable current magnitudes as a function of frequency for selected distances. As can be seen, the ADuM440x are immune and can be affected only by extremely large currents operated at high frequency and very close to the component. For the 1 MHz example noted, one would have to place a 0.5 kA current 5 mm away from the ADuM440x to affect the component's operation.
IDDO = (IDDO (D) + (0.5 x 10 ) x CLVDDO) x (2f - fr) + IDDO (Q) 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).

ADuM4400/ADuM4401/ADuM4402
To calculate the total IDD1 and IDD2, the supply currents for each input and output channel corresponding to IDD1 and IDD2 are calculated and totaled. Figure 8 and Figure 9 provide per channel supply currents as a function of data rate for an unloaded output condition. Figure 10 provides per channel supply current as a function of data rate for a 15 pF output condition. Figure 11 through Figure 15 provide total IDD1 and IDD2 as a function of data rate for ADuM4400/ADuM4401/ ADuM4402 channel configurations. 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 19 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 22 or Figure 23 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 19. Note that the voltage presented in Figure 22 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.

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 ADuM440x. 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 19 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 ADuM440x 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 21, Figure 22, and Figure 23 illustrate these different isolation voltage waveforms. Bipolar ac voltage is the most stringent environment. The goal of a 50-year operating lifetime under the ac bipolar condition determines Analog Devices recommended maximum working voltage.
