AMR based current sensors boost accuracy
ACEINNA MCx1101 family of Current Sensors supports 3.3 volt applications. The highly accurate, wide bandwidth AMR-based current sensors are now available for a wide range of ADC and microprocessor based power systems and applications. The fully integrated, bi-directional devices provide much higher dc accuracy and dynamic range compared with alternative solutions. For example, the ±20A version has a typical accuracy of ±0.6% and are guaranteed to achieve an accuracy of ±2.0% (max) at 85°C. These new current sensors are in an industry standard SOIC-16 package with a low impedance (0.9 milli-ohm) current path and are certified by UL/IEC/EN for isolated applications. These new current sensors also guarantee an offset of ±60mA, or ±0.3% of FSR (max) over temperature, which means that high accuracy can be achieved over a roughly 10:1 range of currents providing significant improvement in dynamic range vs. leading Hall-sensor-based devices.
