Description

The ADuM320N/ADuM321Nare dual-channel digital isolators based on Analog Devices, Inc.,iCoupler®technology. Combining high speed, complementary metal-oxide semiconductor (CMOS) and 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 is 10 ns with a pulse width distortion of less than 3 ns at 5 V operation. Channel matching is hard at 3.0 ns maximum.The ADuM320N/ADuM321N data channels are independent and are available in a variety of configurations with a withstand voltage rating of 5.7 kV RMS and 3.0 kV RMS (for more information, see the Ordering Guide section of the data sheet). The devices operate with the supply voltage on either side ranging from 2.25 V to 5.5 V, providing 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.ApplicationsInvertersPower suppliesIndustrial field bus isolationPWM controller signal isolationGeneral-purpose multichannel isolationProtected by U.S. Patents 5,952,849; 6,873,065; 6,903,578; and 7,075,329.
