ADuM362N: 3.0 kV rms 6-Channel Digital Isolator
The ADuM362N is a 6-channel digital isolator based on Analog Devices, Inc., iCoupler® technology. Combining high speed, complementary metal-oxide semiconductor (CMOS) and back-to-back monolithic air core transformer technology, these isolation components provide outstanding performance characteristics and meet CISPR 32/EN 55032 Class B limits at 5 Mbps.
The maximum propagation delay of the ADuM362N is 10 ns with a pulse-width distortion of less than 3 ns at 5 V operation. Channel matching is tight at 3.0 ns maximum.
The ADuM362N data channels are independent and are available in a variety of configurations with a withstand voltage rating of 3 kV rms (see Figure 17). The devices operate with the supply voltage on either side ranging from 2.25 V to 5.5 V, which provides compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier.
Two different fail-safe options are available, by which the outputs transition to a predetermined state when the input power supply is not applied.
