Opto isolators, or optocouplers, are electronic devices used to enable electrical isolation between two circuits. They are commonly used in industrial, medical, and consumer applications to protect and isolate circuits. The ACPL-4800-000E is a logic output opto isolator from Avago Technologies. In this article, we will discuss the applications and working principles of the ACPL-4800-000E.

The ACPL-4800-000E is a bidirectional logic device with a wide common-mode transient immunity of 600 volts. This device has dual MOSFET output devices with proprietary circuit design, and operates in both forward and reverse logic directions. This isolator offers high data rate transmission with minimal signal distortion, and has an excellent pair-to-pair skew performance. It is also capable of high speed switching with a maximum propagation delay of only 26ns.

The ACPL-4800-000E is typically used in many applications where electrical isolation between two systems is required. These include industrial instrumentation, control systems, medical electronics, automotive systems, and more. In industrial instrumentation, this device is used to provide electrical isolation between two systems for safety or interfacing purposes. In control systems, it is used to protect control circuits from any surge originating from the power lines. It also can be used to isolate two circuits in a medical device for protection against electrical shocks.

As for its working principle, the ACPL-4800-000E consists of a miniature light-emitting diode (LED) that is optically coupled to an integrated photo detector. When the LED is forward biased, it emits light, which is then picked up by the photo detector. The photo detector then switches the output transistor in accordance to the input signal. This switching action provides high common-mode transient immunity, allowing the ACPL-4800-000E to provide high isolation between two systems.

To conclude, the ACPL-4800-000E is a logic output opto isolator from Avago Technologies that is primarily used in various applications requiring electrical isolation between two systems. This device features high data rate transmission and excellent pair-to-pair skew performance, as well as high speed switching with a maximum propagation delay of only 26ns. It functions on the basis of an LED coupled to an integrated photo detector, switching the output transistor in accordance to the input signal.
