产品详情和应用
The ADuM360N/ADuM361N/ADuM362N/ADuM363N are 6-channel digital isolators 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 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 ADuM360N/ADuM361N/ADuM362N/ADuM363N data channels are independent and are available in a variety of configurations with a withstand voltage rating of 3 kV rms (see Figure 28 in Data Sheet). 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.
APPLICATIONS
- Serial-peripheral interface (SPI) data converter isolation
- RS-485 and controller area network with flexible data rate (CAN FD) industrial field bus isolation
- PWM controller signal isolation
- General-purpose multichannel isolation
