ADuM121N Functional Block Diagram APPLICATIONS General-purpose multichannel isolation Industrial field bus isolation GENERAL DESCRIPTION The ADuM120N/ADuM121N1 are 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 superior to alternatives such as optocoupler devices and other integrated couplers. The maximum propagation delay is 13 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 ADuM120N/ADuM121N data channels are independent and are available in a variety of configurations with a withstand voltage rating of 3 kV rms (see the Ordering Guide). The devices operate with the supply voltage on either side ranging from 1.8 V to 5 V, providing compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier. Unlike other optocoupler alternatives, dc correctness is ensured in the absence of input logic transitions. Two different fail-safe options are available in which the outputs transition to a predetermined state when the input power supply is not applied or the inputs are disabled. The ADuM120N0 is pin-compatible with the ADuM1285, and the ADuM120N1 is pin-compatible with the ADuM1280 and the ADuM1200. The ADuM121N0 is pin-compatible with ADuM1286, and the ADuM121N1 is pin-compatible with the ADuM1281 and the ADuM1201. Protected by U.S. Patents 5,952,849; 6,873,065; 6,903,578; and 7,075,329.
