Digital Isolators: The ADUM2400BRIZ-RL application field and working principle

Digital Isolators are used when it is necessary to provide a high degree of electrically isolated signal transmission between two different circuits. Isolators are ideal for preventing transmission of noise and other undesirable signals into sensitive components or circuits. The use of digital isolators is especially important in situations where the potential for high frequency interference exists between the two circuits. The ADUM2400BRIZ-RL is an ideal choice for those looking to protect sensitive circuits.

The Application Field of the ADUM2400BRIZ-RL

The ADUM2400BRIZ-RL is a digital isolator usually used to provide an isolated I/O link between low voltage digital critical systems and standard, low voltage discrete, differential signals. Typical applications of the ADUM2400BRIZ-RL include low voltage sensors and communication systems, where a safe, reliable, and fast isolated I/O link is required. Various communication protocols can be implemented by the ADUM2400BRIG-RL such as CANbus, Modbus, I2C, SPI, and LIN.

Design and Working Principle

The ADUM2400BRIZ-RL is designed with a dual-channel isolated interface, with isolated channels providing a maximum data rate of 5 Mbps. It is a transparent isolator, meaning it transparently passes data and signals without any alteration or processing. The ADUM2400BRIG-RL also features high-level integration, offering a wide operating temperature range, and low power and standby current values.The ADUM2400BRIG-RL uses a planar-magnetic, high speed Optocoupler, which works by transferring data through a magnetic field. This device utilizes a number of components working in tandem to ensure efficient, reliable data transfer between the two isolated circuits.The first component is the LED. An LED emits light when it is supplied with an external current, and the generated light is converted to an electric signal after passing through the Optocoupler’s magnetic core. The second component is the photodetector. The photodetector blocks light waves that are not modulated by the magnetic core, leaving only the modulated light waves, which are then sent back to the LED. The third component is the amplifier, which amplifies the signal to the required level. The isolated signal is then sent to the receiving circuit.

Conclusion

Digital isolators are essential components in low voltage digital design. The ADUM2400BRIZ-RL is an excellent choice of isolator due to its high performance, robust design, and wide operating temperature range. It is a reliable and safe solution for digital isolator designs in a variety of applications.
