Ultra-low Noise Coreless Current Sensor

MP

Description

AK3101 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 compound semiconductor Hall element of high sensitivity and signal processing technology. In addition, since AK3101 has a coreless structure and does not contain magnetic material, it has no hysteresis and is suitable for audio applications. AK3101 is especially suitable for a Motional Feedback system that feedbacks the current of voice coils of the speaker to the amplifier and controls the movement of the voice coils.
AK3101 adopts an ultra-small coreless package which is compliant with safety standards, suitable for applications such as motor control for industrial equipments. Since AK3101 has ultra low noise, it can detect the current by high resolution, which contributes to high-precision torque control of the motor.

Applications

  •                                 Motor control for industrial equipment, Voice coil control for speakers, etc.
