Dual-Channel Isolators with  
Integrated DC/DC Converter, 50 mW  
ADuM5240/ADuM5241/ADuM5242  
GENERAL DESCRIPTION  
Preliminary Technical Data  
FEATURES  
Integrated isolated DC/DC converter  
Regulated 5V/10 mA output  
The ADuM524x1 are dual-channel digital isolators having an  
integrated DC/DC converter. Based on Analog Devices’  
iCoupler® 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  
iCoupler® 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.  
Dual dc-to-10 Mbps (NRZ) signal isolation channels  
Narrow body SOIC 8-lead package  
High temperature operation: 105°C  
Precise timing characteristics:  
3 ns maximum pulse-width distortion  
3 ns maximum channel-to-channel matching  
70 ns maximum propagation delay  
High common-mode transient immunity: > 25 kV/μs  
Safety and regulatory approvals (pending)  
UL recognition  
ADuM524x units may be used in combination or with other  
iCoupler products to achieve greater channel counts.  
2500 V rms for 1 minute per UL 1577  
CSA component acceptance notice #5A  
VDE certificate of conformity  
DIN EN 60747-5-2 (VDE 0884 Part 2): 2003-01  
DIN EN 60950 (VDE 0805): 2001-12; DIN EN 60950: 2000  
VIORM = 425 V peak  
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.
