Product Description
Product Overview
The CQ-330G is an open-type current sensor utilizing a Hall sensor to provide an analog voltage output proportional to AC/DC current. It features a quantum well ultra-thin film InAs Hall sensor for high-accuracy and high-speed current sensing. The coreless, surface-mount VSOP-24 package contributes to space-saving designs. This bi-directional sensor operates on a single 5V power supply and offers a ratiometric output, making it suitable for applications requiring precise and rapid current measurement with high isolation voltage.
