They serve a similar purpose to opt couplers, but opt couplers are too slow and error-prone for high-speed digital signals. Digital isolators only work with digital signals, which are frequently used to transfer digitized versions of analog signals. The resulting signal will have better bandwidth, accuracy, and linearity in comparison to an optocoupler-based system. Industrial control networks use them so that local electronics are not affected by common-mode voltage differences across the network. It has different data rate types and different isolations. The increasing demand for digital isolators in various applications such as Industrial, Healthcare, Automotive, Telecommunications, Aerospace, Defense Energy, and Power, etc., is fueling the growth of the digital isolation market in the near future.
The ground loops are a key cause of unwanted noise in electronic and electric circuits that restricts operations. The digital isolators are used to break ground loops by ensuring that all the circuits have the same ground potential. These digital isolators provide a galvanic path between different ground potentials without effecting the transmission of analog signals through loops. These devices are also helpful in eliminating the electrical noise caused by AC continuity. Therefore, key players have launched digital isolators in the market for noise cancellation in electronic and electrical circuits. Therefore, the demand for digital isolators is increasing, which is fueling the growth of the digital isolator market. Moreover, digital isolators are much safer than ground loops so it has high end use in industrial equipment’s which is propelling the market growth.
Furthermore, the growing demand for vehicle electrification and the governments of different countries worldwide are taking the initiative to formulate regulations for the fast adoption of electric vehicles, which is fueling the demand for digital isolators and further boosting the market growth.
The inability of digital isolators to pass low-frequency signals without modulators has limited their use in various applications, which is hampering the growth of the digital isolator market.
