AK3103 Overview
AK3103 is an open-type current sensor using a Hall sensor which outputs the analog voltage in proportion to the AC/DC current. Ultra low noise property is realized by a III-V pound semiconductor Hall element of high sensitivity and signal processing technology. In addition, since AK3103 has a coreless structure and does not contain magnetic material, it has no hysteresis and is suitable for audio applications.
AK3103 Key Features
