Ultra-low Noise Coreless Current Sensor
EOL
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 equipment's. Since AK3101 has ultra-low noise, it can detect the current by high resolution, which contributes to high-precision torque control of the motor.
Key Features
Ultra-low noise Ultra-low noise is realized by a high-sensitivity compound Hall element and signal processing technology by LSI. High detection current resolution, suitable for high-precision motor torque control.
Coreless structure Since it does not contain a magnetic material, it has no hysteresis and is suitable for audio applications. Especially, it is suitable for a system that controls the movement of the voice coil by feeding back the voice coil current of the speaker (Motional Feedback).
Ultra-small coreless package Adopts ultra-small coreless package that complies with safety standards. We can expect miniaturization of motor control equipment for industrial equipment.
Applications
Motor control for industrial equipment, Voice coil control for speakers, etc.
