Ultra-low Noise Coreless Current Sensor
Ultra-low Noise Coreless Current Sensor
EOL
Description
AK3102 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 AK3102 has a coreless structure and does not contain magnetic material, it has no hysteresis and is suitable for audio applications. AK3102 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. AK3102 adopts an ultra-small coreless package which is compliant with safety standards, suitable for applications such as motor control for industrial equipment's. Since AK3102 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. Therefore, the detection current resolution is high (because of ultra-low noise), and it is suitable for high-precision torque control of the motor.
-
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.
