ADUM3482ARSZ by Analog Devices Inc.

The ADUM3482ARSZ is a cutting-edge digital isolator product from Analog Devices Inc., designed to provide robust isolation for electronic systems. This component is part of the ADuM348x series, which are 4-channel digital isolators with isoPower®, an integrated, isolated dc-to-dc converter. The ADUM3482ARSZ model specifically offers a quad-channel configuration with two forward and two reverse-direction channels.

Featuring Analog Devices' iCoupler® technology, the ADUM3482ARSZ combines high-speed CMOS and monolithic air-core transformer technology to provide outstanding performance characteristics. This technology enables the ADUM3482ARSZ to offer precise and reliable isolation in a small form factor, making it ideal for a wide range of applications including industrial automation, data acquisition systems, and any other systems that require isolation for safety and noise immunity.

The ADUM3482ARSZ operates with an input supply voltage range of 3.0 V to 5.5 V, which allows for flexible integration into various circuit designs. It has a default high output and 3 V to 5.5 V level translation, which simplifies the design process by removing the need for additional level-shifting components.

One of the key features of the ADUM3482ARSZ is its integrated, isolated dc-to-dc converter, which provides up to 500 mW of regulated, isolated power at either 5.0 V from a 5.0 V input or 3.3 V from a 3.3 V input. This feature eliminates the need for a separate isolated power supply, saving space and cost on the PCB.

Additionally, the device boasts a high data rate of up to 25 Mbps and low propagation delay, ensuring fast and accurate signal transmission. The ADUM3482ARSZ also offers robust immunity to electromagnetic interference (EMI) and high transient immunity, which are critical in harsh industrial environments.

For safety and reliability, the ADUM3482ARSZ provides isolation rated at 2.5 kVrms for 1 minute per UL 1577 and VDE V 0884-10 certifications. It is also available in a compact, 16-lead SOIC package, making it suitable for space-constrained applications.

Overall, the ADUM3482ARSZ is a versatile and reliable choice for designers looking to incorporate high-performance isolation with integrated power into their electronic systems.
