Digital Isolators provide safe electrical isolation between two parts of a system to help minimize damage during unexpected surges, faults, and electrical noise. They are available in a wide variety of packages, from miniaturized surface-mount soldered versions to robust, industrial-grade packages. The ADUM152N1BRZ from Analog Devices, Inc. is a compact, industry-leading digital isolator based on Analog Devices’ iCoupler® technology that offers high speed and low latency, plus a low-power design. This technology has been tested and certified for industrial applications, meeting all applicable safety standards for digital isolators.

The ADUM152N1BRZ features integrated channel-to-channel isolation of 3550 VRMS and a typical data rate of 25 Mbps. It features a low operating voltage range of 1.7V to 5.5V, making it suitable for a variety of systems and applications. The ADUM152N1BRZ is available in a 16-pin SOIC package, making it ideal for space-constrained applications.

The ADUM152N1BRZ is designed for a wide variety of applications, from battery-powered systems to high-power equipment. It is suitable for use in medical, industrial, and automotive applications. The digital isolator can be used in systems where a high noise immunity and high isolation is required, such as in factory automation, motor drives, and LED lighting. The ADUM152N1BRZ can also be used for automotive applications, such as door locks, switching power supplies, and HVAC systems.

The ADUM152N1BRZ is designed with a fast switching speed, making it ideal for applications where time-critical data needs to be passed between two systems. It offers an I/O delay of only 1.3 ns, ensuring reliable signal transfer across the channels even under extreme conditions. The I/O channels also feature excellent low power consumption, making it suitable for applications where power is constrained.

The ADUM152N1BRZ utilizes Analog Devices’ iCoupler® technology to allow data transfer between systems through electromagnetic isolation. This technology utilizes coupled transformer coils to create electromagnetic isolation between the input and output channels. This ensures that the input signal does not interact with the output signal, preventing signal distortion and interference.

The ADUM152N1BRZ also includes a monitor function, which allows for additional safety with the dual-channel isolator by providing indication of communication status. This is done by monitoring the status signal of the output channel, as it is connected to the input signal, and using a control register to detect if the two signals match. This ensures that the input and output signals are synchronized, resulting in improved system performance.

The ADUM152N1BRZ provides safe electrical isolation for a variety of systems, including motor drives, factory automation, and automotive applications. Its low power consumption and fast switching speed make it suitable for a wide range of applications. The integrated monitor function allows for improved safety and system performance.
