GENERAL DESCRIPTION
The ADuM7510
on the Analog Devices, Inc., iCoupler® technology. In contrast
to the ADuM1510, the ADuM7510 has a lower isolation rating
offering a reduced cost option for applications that can accept
a 1 kV ac isolation. 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 opto-
couplers. 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 run at
one-tenth to one-sixth the power consumption of optocouplers
at comparable signal data rates.
The ADuM7510 isolator provides five independent isolation
channels supporting data rates up to 10 Mbps. Each side operates
with the supply voltage of 4.5 V to 5.5 V. Unlike other optocoupler
alternatives, the ADuM7510 isolator has a patented refresh
feature that ensures dc correctness in the absence of input logic
transitions and during power-up/power-down conditions.

... DD2 receiving coil is sufficiently large to either falsely set or reset the decoder. The following analysis defines such conditions. The ADuM7510 is examined in a 4.5 V operating condition because it represents the most susceptible mode of operation of this product. The pulses at the transformer output have an amplitude greater than 1.5 V. The decoder has a sensing threshold of about 1.0 V, thereby establishing a 0 ...

... The ADuM7510 is very insensitive to external fields. Only extremely large, high frequency currents, very close to the component can potentially be a concern. For the 1 MHz example noted, a 1.2 kA current must be placed 5 mm away from the ADuM7510 to affect component operation. 1000 100 ...
