Qualified for automotive applications
The ADuM3200/ADuM32011 are dual-channel, digital isolators based on the Analog Devices, Inc., iCoupler® technology.
Combining high speed CMOS and monolithic transformer
technology, these isolation components provide outstanding
performance characteristics superior to alternatives such as
optocoupler devices.
APPLICATIONS
Size-critical multichannel isolation
SPI interface/data converter isolation
RS-232/RS-422/RS-485 transceiver isolation
Digital field bus isolation
Hybrid electric vehicles, battery monitor
By avoiding the use of LEDs and photodiodes, iCoupler
devices remove 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 these iCoupler products. Furthermore, iCoupler devices consume one-tenth to one-sixth the
power of optocouplers at comparable signal data rates.
The ADuM3200/ADuM3201 isolators provide two independent
isolation channels in a variety of channel configurations and
data rates (see the Ordering Guide). They operate with 3.3 V
or 5 V supply voltages on either side, providing compatibility
with lower voltage systems as well as enabling voltage translation
functionality across the isolation barrier. The ADuM3200W
and ADuM3201W are automotive grade versions qualified
for 125°C operation.
In comparison to the ADuM1200/ADuM1201 isolators, the
ADuM3200/ADuM3201 isolators contain various circuit and
layout changes to provide increased capability relative to systemlevel IEC 61000-4-x testing (ESD, burst, and surge). The precise
capability in these tests for either the ADuM1200/ADuM1201
or ADuM3200/ADuM3201 products is strongly determined by
the design and layout of the user board or module. For more
information, see the AN-793 Application Note, ESD/Latch-Up
Considerations with iCoupler Isolation Products.
