CQ-209D
High-Speed Small-Sized Current Sensor
Overview
The CQ-209D is an open-type current sensor using a Hall sensor which outputs the analog voltage
proportional to the AC/DC current. Quantum well ultra-thin film InAs (Indium Arsenide) is used as the Hall
sensor, which enables the high-accuracy and high-speed current sensing. Simple AI-Shell package with the
Hall sensor, magnetic core, and primary conductor realizes the space-saving and high reliability.
Features
- Bidirectional type
- Electrical isolation between the primary conductor and the sensor signal
- 5V single supply operation
- Ratiometric output
- Low variation and low temperature drift of sensitivity and offset voltage
- Low noise output: 2.1mVrms (max.)
- Fast response time: 1μs (typ.)
- Small-sized surface mount package, halogen free
