Specifications: The AMT9221 series are surface-mount current sensors in SOIC-8, offering specifications identical to the AACS730 series: 3.3V/5V supply, ±10A to ±50A ranges, 1% accuracy, 3000Vrms isolation, 250kHz bandwidth, 1.6µs response, and a -40°C to 125°C operating range. Application Scenarios: This series serves as a direct alternative for the same set of medium-current applications. It is ideal for use in industrial automation I/O modules, building automation systems, drone electronic speed controllers (ESCs), and embedded power monitoring in telecom and networking equipment, providing a compact and reliable solution for galvanically isolated current sensing.
