Part details & applications

The ADuM340E/ADuM341E/ADuM342E are quad-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 ADuM340E/ADuM341E/ADuM342E data channels are independent and are available in a variety of configurations with a withstand voltage rating of 5.7 kV rms (see Figure 26 in 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.

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
