Description5-Channel, Unidirectional Digital Isolator
The ADuM15101 is a unidirectional, 5-channel isolator based on the Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as optocoupler devices.

By avoiding the use of LEDs and photodiodes, iCoupler devices eliminate the design difficulties commonly associated with optocouplers. 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 iCoupler products. In addition, iCoupler devices run at one-tenth to one-sixth the power consumption of optocouplers at comparable signal data rates.

The need for external drivers and other discrete components is eliminated with iCoupler products. In addition, iCoupler devices run at one-tenth to one-sixth the power consumption of optocouplers at comparable signal data rates. The ADuM1510 isolator provides five independent isolation channels supporting data rates to 10 Mbps. The ADuM1510 operates with the supply voltage of either side ranging from 5.5 V. Unlike other optocoupler alternatives, the ADuM1510 isolator has a patented refresh feature that ensures dc correctness in the absence of input logic transitions and during power-up/ power-down conditions.

    Supply current values are for all five channels combined running at identical data rates. Output supply current values are specified with no output load present. The supply current associated with an individual channel operating at a given data rate is calculated as described in the Power Consumption section. See Figure 4 through Figure 6 for information on the per-channel supply current as a function of the data rate for unloaded and loaded conditions. See Figure 7 and Figure 8 for total IDD1 and IDD2 supply currents as a function of the data rate for the ADuM1510. 2 The minimum pulse width is the shortest pulse width at which the specified pulse width distortion is guaranteed. Operation below the minimum pulse width is not recommended. 3 The maximum data rate is the fastest data rate at which the specified pulse width distortion is guaranteed. 4 tPHL propagation delay is measured from the 50% level of the falling edge of the VIx signal to the 50% level of the falling edge of the VOx signal. tPLH propagation delay is measured from the 50% level of the rising edge of the VIx signal to the 50% level of the rising edge of the VOx signal. 5 tPSK is the magnitude of the worst-case difference in tPHL and/or tPLH that is measured between units at the same operating temperature, supply voltages, and output load within the recommended operating conditions. 6 Channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels within the same component. 7 CMH is the maximum common-mode voltage slew rate that can be sustained while maintaining VOx × VDD2. CML is the maximum common-mode voltage slew rate that can be sustained while maintaining VOx 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. See Figure 4 through Figure 6 for information on the per-channel supply current as a function of the data rate for unloaded and loaded conditions. See the Power Consumption section for guidance on calculating the per-channel supply current for a given data rate.
