Allegro 电流传感器

High-Accuracy, Isolated Current Sensor with Differential Sensing

ACS724-5

The ACS724/5 current sensors offer precise and stable current measurements in magnetically noisy environments, featuring differential sensing for common-mode rejection, galvanic isolation, and a wide operating temperature range. The ACS724 operates at 5V, while the ACS725 operates at 3.3V.

Product Details

Top Features

  • AEC-Q100 qualified 
  • Differential Hall sensing rejects common-mode fields
  • 1.2 mΩ primary conductor resistance for low power loss and high inrush current withstand capability
  • Integrated shield virtually eliminates capacitive coupling from current conductor to die, greatly suppressing output noise due to high dv/dt transients
  • Industry-leading noise performance with greatly improved bandwidth through proprietary amplifier and filter design techniques
  • High-bandwidth 120 kHz analog output for faster response times in control applications
  • Filter pin allows user to filter the output for improved resolution at lower bandwidth
  • Patented integrated digital temperature compensation circuitry allows for near closed-loop accuracy over temperature in an open-loop sensor
  • Filter pin simplifies bandwidth limiting for better resolution at lower frequencies
  • 5 V, single supply operation
