CSA Component Acceptance Notice 5A VDE certificate of conformity freeing almost 70% of board space compared to isolators packages DIN V VDE V 0884-10 (VDE V 0884-10):2006-12 in wide body SOIC packages. VIORM = 565 VPEAK QSOP package The devices withstand high isolation voltages and meet regulatory VIORM = 849 VPEAK SSOP package requirements, such as UL and CSA standards. In addition to the IECEx and ATEX intrinsic safety space savings, the ADuM1440/ADuM1441/ADuM1442/ Sira 0518 II 1G Ex ia IIC Ga ADuM1445/ADuM1446/ADuM1447 operate with supplies as APPLICATIONS low as 2.25 V. General-purpose, low power multichannel isolation Despite the low power consumption, all models of the ADuM1440/ 1 MHz, low power peripheral interface (SPI) ADuM1441/ADuM1442/ADuM1445/ADuM1446/ADuM1447 4 mA to 20 mA loop process controls provide low, pulse width distortion at <8 ns. In addition, every GENERAL DESCRIPTION model has an input glitch filter to protect against extraneous The ADuM1440/ADuM1441/ADuM1442/ADuM1445/ noise disturbances. 1 ADuM1446/ADuM1447 are micropower, 4-channel digital 1000 isolators based on the Analog Devices, Inc., iCoupler technology. Combining high speed, complementary metal oxide semiconductor 100 (CMOS) and monolithic air core transformer technologies, these isolation components provide outstanding performance characteristics superior to the alternatives, such as optocoupler 10 devices. As shown in Figure 3, in standard operating mode, EN = 0 x when EN = 0 (internal refresh enabled), the current per channel is x EN = 1 x 1 less than 10 A. When EN = 1 (internal refresh disabled), the x current per channel drops to less than 1 A. 0.1 The ADuM1440/ADuM1441/ADuM1442/ADuM1445/ 0.1 1 10 100 1000 10000 ADuM1446/ADuM1447 family of quad 2.5 kV digital isolation DATA RATE (kbps) Figure 3.
