Digital isolators are increasingly preferred over traditional opto-couplers in electrical designs, due to their superior performance in speed, isolation voltage, and control range. The ADUM2211SRWZ-RL is a fault-safe, dual-channel digital isolator, ideally configured as a bridge between two circuits with a wide isolation voltage range (2500 Vrms). This low-profile DIP package isolator is specifically designed for applications requiring redundant control with dual functionality. It includes two sets of LEDs for visual status updates and is compliant with IEC 61000-4-2, IEC 60801-2-3, and ISO 60950-1 standards.

The ADUM2211SRWZ-RL has two active channels, each with an independent input/output, allowing for bidirectional data flow and upper/lower port speed settings. The two input/output channels are widely separated and can communicate with different controllers. When powered, the device is triggered by a logic-level signal, compared against an internal reference, and then amplified to provide the output signal. This isolator is available with two output powers: 3.3V LVCMOS for signal and 5V LVCMOS for power.

The 3.3V and 5V channel options are ideal for applications that require a diverse range of signal compatibility, such as automotive, medical, and industrial applications. The dual capability of the ADUM2211SRWZ-RL makes it convenient for redundant applications and delivers superior performance compared to standard digital isolators. With a 2.4ns maximum propagation delay and 13Mb/s data rate, it is ideal for communication applications such as digital interconnects, bus bridges, or motor controllers.

The ADUM2211SRWZ-RL is a fault-safe digital isolator with built-in ESD and surge protection. It meets IEC 61000-4-2, IEC 60801-2-3, and ISO 60950-1 standards, making it perfect for harsh environments such as automotive, industrial, medical, and avionics applications. In addition, it can detect faults, can include two sets of LEDs for visual status updates, and can be used as a secondary source of power. This combination of features makes the ADUM2211SRWZ-RL one of the best digital isolators available.
