Digital isolators are used to electrically isolate two circuits, to prevent noise, crosstalk, and electromagnetic fields from interfering with the signals and communications of the isolated circuits. The ADUM263N1BRIZ-RL is a type of digital isolator from Analog Devices Inc. that is specifically designed for high-speed data rate applications. In this article, we will look at the application fields and working principle of the ADUM263N1BRIZ-RL digital isolator.
Application Field
The ADUM263N1BRIZ-RL can be used in a wide range of applications due to its high speed data rate. It is especially suitable for noise immunity in high-speed isolator designs such as RS-422, CAN, and USB. The ADUM263N1BRIZ-RL is ideal for industrial and medical applications that require high voltage isolation and Class B (155°C) creepage and clearance requirements. This digital isolator also offers superior performance in EMI/RFI immunity and also delivers a low-cost alternative for replacing opto-couplers in datacom and telecom applications.
Working Principle
The ADUM263N1BRIZ-RL is a sophisticated monolithic isolator, suitable for switching signals up to 500 Mbps. It features analog-like properties and advanced digital isolation technology, meaning that the part is able to maintain high signal integrity while the two sides of the isolation are completely separated. The ADUM263N1BRIZ-RL uses a proprietary capacitive isolation technique which ensures low capacitive coupling between the two sides of the isolation barrier. This type of isolation is designed to ensure that the effects of externally generated EMI/RFI fields, as well as common-mode and transient voltages, are kept from affecting the performance of the circuits. The digital isolator also features excellent temperature stability and low propagation delays.
The ADUM263N1BRIZ-RL is powered by a single 3.3V supply and features an improved slew rate of approximate 1ps on its SCL pin. The SCL pin on the isolator not only offers a wider propagation delay of approximately 4 ns over temperature variations, but also provides an improved noise margin of approximately 5V in order to prevent interference from EMI. Additionally, the ADUM263N1BRIZ-RL offers maximum common mode differential voltages from rail to rail and also features an improved noise immunity of 350/mVpp.
In conclusion, the ADUM263N1BRIZ-RL is a suitable digital isolator for high-speed data rate applications such as RS-422, CAN, and USB. Its advanced digital isolation technology, low capacitive coupling, temperature stability, low propagation delays, and improved noise immunity make it a suitable choice for industrial and medical applications. It is also a great alternative for replacing opto-couplers in datacom and telecom applications and provides superior performance in EMI/RFI immunity.
