The Allegro ACS70331 is a high-sensitivity, 1 MHz GMR-based current sensor IC designed for applications requiring current sensing up to 5 A. Leveraging Giant Magneto-Resistive (GMR) technology, it offers 25 times greater sensitivity than traditional Hall-effect sensors. This enables precise measurement of AC and DC currents with a low-noise, high-speed analog output proportional to the sensed current. The sensor boasts a fast response time of typically 535 ns and operates from a single 3.3 V supply. Its integrated low-resistance primary conductor minimizes power loss, while the differential GMR element configuration provides excellent rejection of stray magnetic fields for stable operation in noisy environments. Available in space-saving QFN-12 and SOIC-8 packages, the ACS70331 is suitable for a wide range of applications, including power monitoring, industrial controls, and consumer electronics.
