The ADUM3481 series quad-channel Digital Isolator based on the Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and monolithic air core transformer technology, this isolation component provides outstanding performance characteristics superior to alternatives such as optocoupler devices and other integrated couplers. With typical propagation delay reduced to 25ns, pulse width distortion is also halved. It is available in a variety of channel configurations with two data rate grades up to 25Mbps. It uses separate core and I/O power supplies. The core operates between 3 and 5.5V, whereas the I/O supply can range from 1.8 to 5.5V. If I/O operation is required within the range of the core supply, the two supplies can be tied together to allow single-supply operation. When the I/O must interface with logic levels that are different from the core supply voltage, the I/O supply operates independently of the core supply over its wider range.
● Up to 25Mbps data rate (NRZ)
● Low dynamic power consumption
● Output default select
● >25kV/µs High common-mode transient immunity
