Quad-Channel Isolator with Integrated DC-to-DC Converter Data Sheet ADuM5400 FEATURES GENERAL DESCRIPTION iso Power integrated, isolated dc-to-dc converter
The ADuM54001 device is a quad-channel digital isolator with
Regulated 5 V output
isoPower®, an integrated, isolated dc-to-dc converter. Based on
500 mW output power
the Analog Devices, Inc., iCoupler® technology, the dc-to-dc
Quad dc-to-25 Mbps (NRZ) signal isolation channels
converter provides up to 500 mW of regulated, isolated power
Schmitt trigger inputs
with 5.0 V input and 5.0 V output voltages. This architecture
16-lead SOIC package with >7.6 mm creepage
eliminates the need for a separate, isolated dc-to-dc converter in
High temperature operation: 105°C maximum
low power, isolated designs. The iCoupler chip scale transformer
High common-mode transient immunity: >25 kV/μs
technology is used to isolate the logic signals and the magnetic

2500 V rms for 1 minute per UL 1577
The ADuM5400 isolator provides four independent isolation
