ADUM131D1BRWZ-RL

The ADUM131D1BRWZ-RL digital isolator redefines signal integrity with its exceptional features. It boasts 100 kV/μs common-mode transient immunity, robust resistance to noise, and low propagation delay of 13 ns (5V) and 15 ns (1.8V). With a maximum data rate of 150 Mbps, it ensures swift communication. The isolator holds pending safety approvals, UL recognition, VDE conformity, and VIORM of 849 V peak, solidifying its reliability in high-voltage settings. The ADUM131D1BRWZ-RL stands as a beacon of signal protection and efficiency in the realm of digital isolation technology.

·Industrial field bus isolation

The ADuM130D/ADuM130E/ADuM131D/ADuM131E1 are triple-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 ADuM130D/ADuM130E/ADuM131D/ADuM131E data channels are independent and are available in a variety of configurations with a withstand voltage rating of 3.0 kV rms or 3.75 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 ADuM130E1/ADuM131E1 are pincompatible with the ADuM1300/ADuM1301.
