GENERAL DESCRIPTION
The ADuM1210
1
is a dual-channel, digital isolator based on
Analog Devices’
i
Coupler technology. Combining high speed
CMOS and monolithic transformer technology, this isolation
component provides outstanding performance characteristics
superior to alternatives such as optocoupler devices.
By avoiding the use of LEDs and photodiodes,
i
Coupler devices
remove the design difficulties commonly associated with
optocouplers. The concerns of the typical optocoupler
regarding uncertain current transfer ratios, nonlinear transfer
functions, and temperature and lifetime effects are eliminated
with the simple,
i
Coupler digital interfaces and stable
performance characteristics. The need for external drivers and
other discrete components is eliminated with
i
Coupler products.
Furthermore,
i
Coupler devices consume one-tenth to one-sixth
the power of optocouplers at comparable signal data rates.
The ADuM1210 isolator provides two independent isolation
channels operable with the supply voltage on either side ranging
from 2.7 V to 5.5 V. This provides compatibility with lower
voltage systems as well as enabling a voltage translation
functionality across the isolation barrier. In addition, the
ADuM1210 provides low pulse-width distortion (<3 ns) and
tight channel-to-channel matching (<3 ns). Unlike other
optocoupler alternatives, the ADuM1210 isolator has a patented
refresh feature that ensures dc correctness in the absence of
input logic transitions and during power-up/power-down
conditions. Furthermore, as an alternative to the
ADuM1200
dual-channel, digital isolator that defaults to an output high
condition, the ADuM1210’s outputs default to a logic low state
when input power is off.
