Digital isolators are electrical components which provide physical insulation between two circuits while still allowing digital signals to pass between them. The ADUM3480BRSZ is a popular digital isolator, used to provide digital isolation between two circuits at a data rate of up to 15 Mbps, while allowing for 32-bit data transfers. The ADUM3480BRSZ offers extremely low power consumption, with an quiescent current of only 1.4uA. It also provides for a low gate control current of 2.3uA.

The ADUM3480BRSZ is an ideal choice for many applications, including high-speed signal isolation, signal conversion, and protection circuits. It is used in a variety of industrial, consumer, and medical applications, such as:

• Motor control systems
• Power distribution systems
• Digital input / output interfaces
• Industrial control systems
• Medical diagnostic equipment
• Consumer electronic products

The ADUM3480BRSZ is often used to eliminate the need for an optocoupler, as it provides galvanic isolation between two circuits. This isolator utilizes the patented iCoupler technology, allowing for very fast and low-power signal transfers. The iCoupler technology eliminates the data line transients or glitches which can commonly occur in signal transmissions, providing for very reliable signal transfers of up to 15 Mbps.

The working principle of the ADUM3480BRSZ is that it uses optically coupled surface-mount isolation components, which allow the transmission of digital signals between two circuits while maintaining electrical isolation. The ADUM3480BRSZ utilizes a pair of chips which are optically isolated from each other. The “master” chip is the source of the digital signal, while the “slave” chip is the recipient of the digital signal. The master chip transmits the digital signal to the slave chip via an optically coupled LED and phototransistor pathway. This optically-coupled pathway provides the electrical isolation between the two chips, while allowing for fast and secure data transmissions.

The ADUM3480BRSZ also offers additional features such as protection against voltage transients, noise, and over-voltage events. The protection circuits also provide isolation between input and output pins, further ensuring safety and reliability when using the ADUM3480BRSZ for signal transmission.

In summary, the ADUM3480BRSZ is an ideal solution for many applications, as it offers very low power consumption, fast data transfer speeds, and reliable electrical isolation between two circuits. It is used in a variety of industrial, consumer, and medical applications, and its wide range of features make it an attractive choice for many digital isolation applications.
