ADUM150N1BRZ-RL7

The ADUM150N1BRZ-RL7 digital isolator stands out for its outstanding features, including high common-mode transient immunity of 100 kV/μs, robust immunity to radiated and conducted noise, low propagation delay (13 ns for 5 V and 15 ns for 1.8 V operation), and a maximum guaranteed data rate of 150 Mbps. Also available in a narrow 16-pin, RoHS-compliant SOIC package, the digital isolator is a versatile and reliable solution for a wide variety of demanding applications.

·General-purpose multichannel isolation

·Serial peripheral interface (SPI)/data converter isolation

·Industrial field bus isolation

The ADuM150N/ADuM151N/ADuM152N1 are 5-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 4.5 ns at 5 V operation. Channel to channel matching of propagation delay is tight at 4.0 ns maximum.

The ADuM150N/ADuM151N/ADuM152N data channels are independent and are available in a variety of configurations with a withstand voltage rating of 3.0 kV rms (see the Ordering Guide). The devices operate with the supply voltage on either side ranging from 1.7 V to 5.5 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 by which the outputs transition to a predetermined state when the input power supply is not applied.
