GENERAL DESCRIPTION
The ADuM1440/ADuM1441/ADuM1442/ADuM1445/
ADuM1446/ADuM1447
1
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 EN
x
= 0 (internal refresh enabled), the current per channel is
less than 10 μA. When EN
x
= 1 (internal refresh disabled), the
current per channel drops to less than 1 μA.
The ADuM1440/ADuM1441/ADuM1442/ADuM1445/
ADuM1446/ADuM1447 family of quad 2.5 kV digital isolation
devices are packaged in a small 16-lead QSOP and 20-lead SSOP,

freeing almost 70% of board space compared to isolators packages
in wide body SOIC packages.
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.
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.
