GENERAL DESCRIPTION
The ADuM75101 is a unidirectional 5-channel isolator based
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
www.DacutarSrehnetettr4aUns.cfeormratios, 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.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
