AK3101 - Ultra Low Noise Coreless Current Sensor

General 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.

Key Features

  • Ultra low noise : -102 dBm / √ Hz (integrated noise 0.7 mVrms, 100 Hz to 200 kHz integration).
  • No hysteresis output, because of not containing the magnetic material.
  • Very small primary conductor resistance : 1.6 mΩ.
  • High Accuracy : 1.5% F. S. (Ta = -40 to 90 °C Typ. ).
  • Small and thin surface mount package : 7.9 mm × 7.6 mm × 1.15 mm.
  • Certified with safety standards of IEC / UL 60950, UL 1577 certification pending.
  • Isolation voltage :.

[AK3101] AK3101 Ultra Low Noise Coreless Current Sensor 1. General 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.
