Product Details
| 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. Ultralow power operation 3.3 V operation 5.6 μA per channel quiescent current, refresh enabled 0.3 μA per channel quiescent current, refresh disabled 148 μA/Mbps per channel typical dynamic current 2.5 V operation 3.1 μA per channel quiescent current, refresh enabled 0.1 μA per channel quiescent current, refresh disabled 116 μA/Mbps per channel typical dynamic current Small, 20-lead SSOP package and small 8-lead SOIC package Bidirectional communication Up to 2 Mbps data rate nonreturn to zero (NRZ) High temperature operation: 125°C High common-mode transient immunity: >25 kV/μs Safety and Regulatory Approvals UL 1577 component recognition program (pending) 3750 V rms for 1 minute per UL 1577 (20-lead SSOP) 3000 V rms for 1 minute per UL 1577 (8-lead SOIC) CSA Component Acceptance Notice 5A (pending) VDE certificate of conformity (pending) DIN V VDE V 0884-10 (VDE V 0884-10): 2006-12 VIORM = 849 V peak (20-lead SSOP) VIORM = 560 V peak (8-lead SOIC) General-purpose, low power, multichannel isolation 1 MHz low power serial peripheral interface (SPI) 4 mA to 20 mA loop process control |
