Digital isolators are crucial components in a wide range of applications. They enable reliable data transmission between isolated circuits, allowing engineers to connect devices without compromising performance. One such device is the ADUM2402ARWZ, which is ideal for high speed bidirectional digital isolation. In this article, we explain the application field and working principle of the ADUM2402ARWZ.
Application Field
The ADUM2402ARWZ digital isolator is designed for high bandwidth, bidirectional digital isolation applications. This device is particularly useful for applications involving power line communication or where space is limited. Examples of these include automotive network isolators, industrial automation, medical equipment, power monitor systems, and Ethernet and USB isolation. Additionally, the ADUM2402ARWZ can also be used in various consumer electronic applications such as AV receivers, DVD players, and LCD/LED televisions.
Working Principle
The ADUM2402ARWZ is a digital isolator that operates by converting electrical pulses to light (digital optical isolation). When it receives an electric pulse on the input side, it emits a proportional light pulse, which is then converted back on the output side into an electrical pulse. This allows data to be transmitted between two or more isolated circuits without any electrical contact between them.
The device consists of two SMT packaged ICs; one for the input side and one for the output side. The input side of the ADUM2402ARWZ contains a high-efficiency LED and an optocoupler, while the output side contains a photodiode, an amplifier, and a voltage comparator. The LED emits light when a voltage is applied to it, generating a light pulse. This light pulse is then collected by the optocoupler, and the photodiode on the opposite side also converts the light pulse back into an electrical pulse. The amplifier and voltage comparator then condition and compare the voltage and generate a signal that can be used by the system.
The ADUM2402ARWZ is designed to achieve data rates up to 20 Mbps with a high isolation voltage of 3750V. It also has a low power consumption of 2.1 mW when operating at 10 Mbps, making it ideal for applications where power consumption is a primary concern. Additionally, the device is also designed to be immune to EMI and RFI noise, allowing signals to be reliably transmitted even in electrically noisy environments.
Conclusion
The ADUM2402ARWZ is an ideal choice for high speed bidirectional digital isolation applications. It is particularly useful in applications where space is limited or where power consumption is a primary concern. Furthermore, the device is designed to operate reliably in electrically noisy environments, making it suitable for a wide range of applications. This digital isolator is a great choice for engineers looking for an effective solution for their data transmission needs.
