ADUM162N1BRZ-RL7

The ADUM162N1BRZ-RL7 standard digital isolator offers high common-mode transient immunity (100 kV/μs), robust resistance to radiated and conducted noise, low propagation delay (13 ns max for 5 V, 15 ns max for 1.8 V), and a maximum guaranteed data rate of 150 Mbps. It excels in low dynamic power consumption, provides voltage level translation between 1.8 V and 5 V, operates at high temperatures (up to 125°C), and features fail-safe high and low options. All of these capabilities are packaged in a compact 16-lead, RoHS-compliant, narrow-body SOIC package, making it an ideal choice for a wide range of industrial and commercial applications.

·General-purpose multichannel isolation

·Serial peripheral interface (SPI)/data converter isolation

·Industrial field bus isolation

The ADuM160N/ADuM161N/ADuM162N/ADuM163N1 are 6-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 ADuM160N/ADuM161N/ADuM162N/ADuM163N 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.
