The ACS70331EESATR-2P5B3 from Allegro Microsystems is a GMR-based current sensor IC optimized for sensing currents up to ±2.5A. It features a high sensitivity and a 1MHz bandwidth, enabling a fast response time of typically 535ns. This sensor operates from a single 3.3V supply and provides a non-ratiometric analog voltage output proportional to both AC and DC current.
The device incorporates giant magneto-resistive (GMR) technology, offering significantly higher sensitivity compared to traditional Hall-effect sensors. Its differential configuration provides excellent rejection of stray magnetic fields, ensuring stable operation in noisy environments. The low primary conductor resistance of 1.1 mΩ minimizes power loss.
Designed for space-constrained applications, the ACS70331EESATR-2P5B3 is available in a compact 12-QFN (3x3) surface-mount package. It operates over a commercial temperature range of -40°C to 85°C.
This device is approaching end-of-life, with a Last Time Buy phase expected to begin within six months from February 2, 2026.
