APPLICATIONS

General-purpose, low power multichannel isolation 1 MHz, low power peripheral interface (SPI) 20 mA loop process controls

The ADuM1440/ADuM1441/ADuM1442/ADuM1445/ ADuM1446/ADuM1447 family of quad 2.5 kV digital isolation devices are packaged in a small 16-lead QSOP, 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 (pending). In addition to the space savings, the ADuM1440/ADuM1441/ADuM1442/ADuM1445/ADuM1446/ ADuM1447 operate with supplies as low 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.

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 2, in standard operating mode, when ENx = 0 (internal refresh enabled), the current per channel is less than 10 �A. When ENx = 1 (internal refresh disabled), the current per channel drops to less than 1 �A.
