The CQ-2235 is a high-speed, small-sized, open-type current sensor that utilizes a Quantum Well ultra-thin film InAs Hall sensor. It provides an analog voltage output proportional to AC/DC current, enabling high-accuracy and high-speed current sensing. The integrated AI-Shell package, combining the Hall sensor, magnetic core, and primary conductor, ensures space-saving design and high reliability. It is suitable for applications requiring electrical isolation between the primary conductor and the sensor signal, operating on a 3.3V single supply.
