High-Sensitivity TMR Magnetic Field Sensor MMLH45F

Product Announcement from MultiDimension Technology Co., Ltd.

The MDT MMLH45F TMR linear sensor features very-high sensitivity at 12 mV/V/Oe, very-low power consumption at 12.5μW, wide operating field range at +/-50 Oe, low hysteresis at 1%FS, and excellent thermal stability over -40°C - 125°C. Designed with TMR (Tunneling Magnetoresistance) technology, a unique push-pull full bridge composed of four TMR elements provides a high sensitivity voltage output that is linearly proportional to a magnetic field applied parallel to the surface of the sensor package. The MMLH45F linear sensor is suitable for a variety of magnetic sensor applications under diverse operating conditions. It is available in a 6mm x 5mm x 1.7mm SOP8 package.
