Description

CQ-209A 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.

Key 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 package, halogen free
