CQ-320x and CQ-330x Current Sensors

AKM's CQ-320x and CQ-330x family of high-speed response coreless current sensors

Image of AKM Semiconductors' CQ-320x and CQ-330x Current SensorsAKM’s CQ-320x and CQ-330x families are coreless open-type magnetic current sensors using a Hall sensor which outputs the analog voltage proportional to the AC/DC current. Quantum well ultra-thin film InAs (Indium Arsenide) is used as the Hall sensor, which enables high accuracy and high speed current sensing. The families are offered in both a small space-saving VSOP package size, high sensitivity, and high galvanic isolation. The CQ-320x is offered in a 3.3 V single power supply and the CQ-330x is offered in a 5.0 V single power supply.

Features
  • Small sized surface mount package: VSOP-24 
  • Size: (D/W/H) 7.9 mm x 7.6 mm x 1.15 mm
  • CQ-320x single power supply 3.0 V
  • CQ-330x single power supply 5.0 V
  • Excellent temperature stability
  • High isolation voltage: 3.0 kV (50 Hz/60 Hz, 60 s)
  • Ultra-fast response time: 0.5 us typical
  • No output hysteresis
  • Ratiometric output
