Dual-Channel Digital Isolators  
ADuM1200/ADuM1201  
GENERAL DESCRIPTION  
FEATURES  
Narrow body SOIC 8-lead package  
Low power operation  
5 V operation  
The ADuM120x are dual-channel digital isolators based on  
Analog Devices’ iCoupler® technology. Combining high speed  
CMOS and monolithic transformer technology, these isolation  
components provide outstanding performance characteristics  
superior to alternatives such as optocoupler devices.  
1.1 mA per channel maximum @ 0 Mbps to 2 Mbps  
3.7 mA per channel maximum @ 10 Mbps  
8.2 mA per channel maximum @ 25 Mbps  
3 V operation  
0.8 mA per channel maximum @ 0 Mbps to 2 Mbps  
2.2 mA per channel maximum @ 10 Mbps  
4.8 mA per channel maximum @ 25 Mbps  
Bidirectional communication  
By avoiding the use of LEDs and photodiodes, iCoupler devices  
remove the design difficulties commonly associated with  
optocouplers. The typical optocoupler concerns regarding  
uncertain current transfer ratios, nonlinear transfer functions,  
and temperature and lifetime effects are eliminated with the  
simple iCoupler digital interfaces and stable performance  
characteristics. The need for external drivers and other discrete  
components is eliminated with these iCoupler products.  
Furthermore, iCoupler devices consume one-tenth to one-sixth  
the power of optocouplers at comparable signal data rates.  
3 V/5 V level translation  
High temperature operation: 105°C  
High data rate: dc to 25 Mbps (NRZ)  
Precise timing characteristics  
3 ns maximum pulse-width distortion  
3 ns maximum channel-to-channel matching  
High common-mode transient immunity: > 25 kV/µs  
Safety and regulatory approvals  
UL recognition  
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 = 560 V peak  
The ADuM120x isolators provide two independent isolation  
channels in a variety of channel configurations and data rates  
(see the Ordering Guide). Both parts 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. In  
addition, the ADuM120x provide low pulse-width distortion  
(< 3 ns for CR grade) and tight channel-to-channel matching  
(< 3 ns for CR grade). Unlike other optocoupler alternatives, the  
ADuM120x isolators have a patented refresh feature that  
ensures dc correctness in the absence of input logic transitions  
and during power-up/power-down conditions.  
APPLICATIONS  
Size-critical multichannel isolation  
SPI® interface/data converter isolation  
RS-232/RS-422/RS-485 transceiver isolation  
Digital field bus isolation
