Moreover, this device offers magnetic field isolation for protection against electrical noise, which makes it ideal for use in mobile phones or other communication systems. It can also be used in industrial systems, such as in automotive or panel meters, and it is also commonly used in security systems.

Working Principle

TheVO1263AB optoisolator incorporates an array of photovoltaic detector cells in a coplanar configuration, which enables voltage to be generated by zero crossing detection when exposed to light. Each cell is constructed using a negatively charged photodiode, and a positively charged source. The differential voltage generated by the two opposing electron beams is then detected and amplified by a linear array. This enables the signal to be fully isolated from any other ground references.

The optoisolator offers wide bandwidth operation, with a response time of 1 microsecond, making it ideal for high speed data transmission applications. Additionally, it features a low power dissipation mode, allowing for efficient power consumption. Finally, it offers high-resistance insulation for superior noise immunity, making it the optimal choice for interference-sensitive applications.

TheVO1263AB optoisolator is a versatile device with a wide application field and excellent performance. It is suitable for many applications, providing efficient data transmission and superior noise immunity, and it offers a wide range of advantages.
