Combining high speed CMOS and monolithic air core transformer technology, this isolation component provides outstanding performance characteristics superior to alternatives, such as optocoupler devices. Configured as a pin-compatible replacement for existing high speed optocouplers, the ADuM1100 supports data rates as high as 25 Mbps and 100 Mbps. The ADuM1100 operates with a voltage supply ranging from 3.0 V to 5.5 V, boasts a propagation delay of <18 ns and edge asymmetry of <2 ns, and is compatible with temperatures up to 125°C. It operates at very low power, less than 0.9 mA of quiescent current (sum of both sides), and a dynamic current of less than 160 μA per Mbps of data rate. Unlike other optocoupler alternatives, the ADuM1100 provides dc correctness with a patented refresh feature that continuously updates the output signal. The ADuM1100 is offered in three grades. The ADuM1100AR and ADuM1100BR can operate up to a maximum temperature of 105°C and support data rates up to 25 Mbps and 100 Mbps, respectively. The ADuM1100UR can operate up to a maximum temperature of 125°C and supports data rates up to 100 Mbps.

I | Page 15 of 20 5.5 ADuM1100 Data Sheet APPLICATION INFORMATION Pulse width distortion is the maximum difference between tPLH and tPHL and provides an indication of how accurately the input signal’s timing is preserved in the component’s output signal. Propagation delay skew is the difference between the minimum and maximum propagation delay values among multiple ADuM1100 components operated at the same operating temperature and having the same output load. PC BOARD LAYOUT The ADuM1100 digital isolator requires no external interface circuitry for the logic interfaces. A bypass capacitor is recommended at the input and output supply pins. The input bypass capacitor can conveniently be connected between Pin 3 and Pin 4 (see Figure 13). Alternatively, the bypass capacitor can be located between Pin 1 and Pin 4. The output bypass capacitor can be connected between Pin 7 and Pin 8 or Pin 5 and Pin 8. The capacitor value should be between 0.01 μF and 0.1 μF. The total lead length between both ends of the capacitor and the power supply pins should not exceed 20 mm. VDD1 Depending on the input signal rise/fall time, the measured propagation delay based on the input 50% level can vary from the true propagation delay of the component (as measured from its input switching threshold). This is because the input threshold, as is the case with commonly used optocouplers, is at a different voltage level than the 50% point of typical input signals. This propagation delay difference is given by VDD2 VI (DATA IN) VO (DATA OUT) GND1 GND2 02462-013 (OPTIONAL) ΔLH = t′PLH − tPLH = (tR/0.8 VI)(0.5 VI − VITH (L-H)) Figure 13. Recommended Printed Circuit Board Layout ΔHL = t′PHL − tPHL = (tF/0.8 VI)(0.5 VI − VITH (H-L)) See the AN-1109 Application Note for board layout guidelines. where: tPLH and tPHL are the propagation delays as measured from the input 50% level. t’PLH and t’PHL are the propagation delays as measured from the input switching thresholds. tR and tF are the input 10% to 90% rise/fall times. VI is the amplitude of the input signal (0 V to VI levels assumed). VITH (L–H) and VITH (H–L) are the input switching thresholds. PROPAGATION DELAY-RELATED PARAMETERS Propagation delay time describes the length of time it takes for a logic signal to propagate through a component. Propagation delay time to logic low output and propagation delay time to logic high output refer to the duration between an input signal transition and the respective output signal transition (see Figure 14).

Typical Pulse Width Distortion Adjustment Due to Input Rise/Fall Time Variation (for VDD1 = 3.3 V and 5 V) METHOD OF OPERATION, DC CORRECTNESS, AND MAGNETIC FIELD IMMUNITY 0 The two coils in Figure 1 act as a pulse transformer. Positive and negative logic transitions at the isolator input cause narrow (2 ns) pulses to be sent via the transformer to the decoder. The decoder is bistable and 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 μs, a periodic update pulse of the appropriate polarity is sent to ensure dc correctness at the output. If the decoder receives none of these update pulses for more than about 5 μs, the input side is assumed to be unpowered or nonfunctional, in which case the isolator output is forced to a logic high state by the watchdog timer circuit. –1 5V INPUT SIGNAL –2 3.3V INPUT SIGNAL –3 02462-017 PROPAGATION DELAY CHANGE, ∆HL (ns) 5 02462-018 PULSE WIDTH DISTORTION ADJUSTMENT, ∆PWD (ns) 6 02462-016 PROPAGATION DELAY CHANGE, ∆LH (ns) 4 –4 1 2 3 4 5 6 7 8 INPUT RISE TIME (10%–90%, ns) 9 10 Figure 17. Typical Propagation Delay Change Due to Input Fall Time Variation (for VDD1 = 3.3 V and 5 V) The impact of the slower input edge rates can also affect the measured pulse width distortion as based on the input 50% level. This impact can either increase or decrease the apparent pulse width distortion depending on the relative magnitudes of tPHL, tPLH, and PWD. The case of interest here is the condition that leads to the largest increase in pulse width distortion. The change in this case is given by ΔPWD = PWD′ − PWD = ΔLH − ΔHL = (t/0.8 VI)(V − VITH (L-H) − VITH (H-L)), (for t = tR = tF) where: PWD = |tPLH − tPHL|. PWD’ = |t’PLH − t’PHL|. This adjustment in pulse width distortion is plotted as a function of input rise/fall time in Figure 18. The limitation on the magnetic field immunity of the ADuM1100 is set by the condition in which induced voltage in the transformer’s receiving coil is sufficiently large to either falsely set or reset the decoder. The analysis that follows defines the conditions under which this can occur. The 3.3 V operating condition of the ADuM1100 is examined because it represents the most susceptible mode of operation. The pulses at the transformer output are greater than 1.0 V in amplitude. The decoder has sensing thresholds 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 V = (−dβ/dt) ∑π rn2, n = 1, 2, . . . , N where: β 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). Rev.

Maximum Allowable Current for Various Current-to-ADuM1100 Spacings 02462-019 MAXIMUM ALLOWABLE MAGNETIC FLUX DENSITY (kgauss) 100 1000 MAXIMUM ALLOWABLE CURRENT (kA) Given the geometry of the receiving coil in the ADuM1100 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. 10k 100k 1M 10M 100M MAGNETIC FIELD FREQUENCY (Hz) Figure 19. Maximum Allowable External Magnetic Field 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 ADuM1100 transformers. Figure 20 expresses these allowable current magnitudes as a function of frequency for selected distances. As can be seen, the ADuM1100 is extremely 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 current of 0.5 kA 5 mm away from the ADuM1100 to affect the component’s operation. Note that at combinations of strong magnetic field and high frequency, any loops formed by printed circuit board traces could 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. POWER CONSUMPTION The supply current of the ADuM1100 isolator is a function of the supply voltage, the input data rate, and the output load. The input supply current is given by IDDI = IDDI (Q) f ≤ 0.5fr IDDI = IDDI (D) × (2f − fr) + IDDI (Q) f > 0.5fr The output supply current is given by IDDO = IDDO (Q) f ≤ 0.5fr −3 IDDO = (IDDO (D) + (0.5 × 10 ) × CLVDDO) × (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 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). Rev.
