The devices withstand high isolation voltages and meet regulatory  
requirements, such as UL and CSA standards. In addition to the  
space savings, the ADuM1440/ADuM1441/ADuM1442/  
ADuM1445/ADuM1446/ADuM1447 operate with supplies as  
low as 2.25 V.

APPLICATIONS  
General-purpose, low power multichannel isolation  
1 MHz, low power peripheral interface (SPI)  
4 mA to 20 mA loop process controls  
Despite the low power consumption, all models of the ADuM1440/  
ADuM1441/ADuM1442/ADuM1445/ADuM1446/ADuM1447  
provide low, pulse width distortion at <8 ns. In addition, every  
model has an input glitch filter to protect against extraneous  
noise disturbances.  
GENERAL DESCRIPTION  
The ADuM1440/ADuM1441/ADuM1442/ADuM1445/  
ADuM1446/ADuM14471 are micropower, 4-channel digital  
isolators based on the Analog Devices, Inc., iCoupler® technology.  
Combining high speed, complementary metal oxide semiconductor  
(CMOS) and monolithic air core transformer technologies,  
these isolation components provide outstanding performance  
characteristics superior to the alternatives, such as optocoupler  
devices. As shown in Figure 3, in standard operating mode,  
when ENx = 0 (internal refresh enabled), the current per channel is  
less than 10 μA. When ENx = 1 (internal refresh disabled), the  
current per channel drops to less than 1 μA.
