The need for the Analog Devices, Inc., iCoupler technology. In contrast to external drivers and other discrete components is eliminated with the ADuM1510, the ADuM7510 has a lower isolation rating, these iCoupler products. Furthermore, iCoupler devices run at offering a reduced cost option for applications that can accept one-tenth to one-sixth the power consumption of optocouplers a 1 kV ac isolation. Combining high speed CMOS and monolithic at comparable signal data rates. air core transformer technology, these isolation components The ADuM7510 isolator provides five independent isolation provide outstanding performance characteristics superior to channels supporting data rates up to 10 Mbps. Each side operates alternatives such as optocoupler devices. with the supply voltage of 4.5 V to 5.5 V. Unlike other optocoupler By avoiding the use of LEDs and photodiodes, iCoupler devices alternatives, the ADuM7510 isolator has a patented refresh eliminate the design difficulties commonly associated with opto- feature that ensures dc correctness in the absence of input logic couplers. The typical optocoupler concerns regarding uncertain transitions and during power-up/power-down conditions. current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects are eliminated with the simple iCoupler digital 1 Protected by U.S. Patents 5,952,849 6,873,065 and 7,075,329.
