APPLICATIONS
The ADuM440x¹ are 4-channel digital isolators 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 that are superior to the alternatives, such as
optocoupler devices and other integrated couplers.
The ADuM440x isolators provide four independent isolation
channels in a variety of channel configurations and data rates
(see the Ordering Guide). All models operate with the supply
voltage on either side ranging from 2.7 V to 5.5 V, providing
compatibility with lower voltage systems as well as enabling a
voltage translation functionality across the isolation barrier.
The ADuM440x isolators have a patented refresh feature that
ensures dc correctness in the absence of input logic transitions
and during power-up/power-down conditions.
This family of isolators, like many Analog Devices isolators,
offers very low power consumption, consuming one-tenth to
one-sixth the power of comparable isolators at comparable data
rates up to 10 Mbps. All models of the ADuM440x provide low
pulse width distortion (<2 ns for C grade). In addition, every
model has an input glitch filter to protect against extraneous noise
disturbances.
The ADuM440x contain circuit and layout enhancements to help
achieve system-level IEC 61000-4-x compliance (ESD/burst/surge).
The precise capability in these tests for the ADuM440x are strongly
determined by the design and layout of the user’s board or module.
