Allegro MicroSystems Inc. High-Accuracy, 3.3V Isolated Current Sensor with Stray Field Rejection ACS725LLCTR-10AB-T

The ACS725LLCTR-10AB-T is an automotive-grade, galvanically isolated current sensor IC in an SOIC8 package, designed for accurate AC or DC current sensing in space-constrained applications. It features a 1.2 mΩ primary conductor resistance, differential Hall sensing for common-mode field rejection, and a 120 kHz bandwidth analog output. Operated from a 3.3 V single supply, it provides a ratiometric output with factory-trimmed sensitivity of 132 mV/A for a ±10 A measurement range. The device is AEC-Q100 qualified, includes an integrated shield for dV/dt noise suppression, and supports optional bandwidth filtering via a dedicated pin. The package is a low-profile SOIC8 with 100% matte tin plating, and its solder bumps are Pb-based, compliant with RoHS exemptions. Operating temperature range is from -40°C to 150°C.
