GENERAL DESCRIPTION
The ADuM524x
1
are dual-channel digital isolators having an
integrated DC/DC converter. Based on Analog Devices’
i
Coupler technology, the DC/DC converter provides up to
50 mW of regulated, isolated power at +5V. This eliminates the
need for a separate isolated DC/DC converter in low-power
isolated designs. Analog Devices’ chip-scale transformer
i
Coupler
technology is used both for the isolation of the logic
signals as well as for the DC/DC converter. The result is a small
form-factor total-isolation solution.
ADuM524x units may be used in combination or with other
i
Coupler products to achieve greater channel counts.
The ADuM524x isolators provide two independent isolation
channels in a variety of channel configurations and data rates
(see Ordering Guide) operating off a 5V input supply.
