GENERAL DESCRIPTION
The ADuM1240/ADuM1241/ADuM1245/ADuM12461 are
micropower, 2-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.
The 20-lead SSOP version of the ADuM1240/ADuM1241/
ADuM1245/ADuM1246 allows control of the internal refresh
functions. 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.
The ADuM1240/ADuM1241/ADuM1245/ADuM1246 are
packaged in either a 20-lead SSOP for 3.75 kV reinforced
isolation or an 8-lead SOIC for 3 kV basic isolation. The devices
meet regulatory requirements, such as UL and CSA standards.
In addition to the space saving package options, the ADuM1240/
ADuM1241/ADuM1245/ADuM1246 operate with supplies as
low as 2.25 V. All models provide low, pulse width distortion at
<8 ns. In addition, every model has an input glitch filter to
protect against extraneous noise disturbances.
