MDT Multidimensional Technology TMR9112 ultra-high sensitivity, extremely low noise TMR linear sensor and initialization coil

Introduction

The magnetoresistive Wheatstone bridge of the TMR9112 sensor can be driven by voltage or current,and can be configured to stably measure magnetic fields even when exposed to large magnetic fields or at extremely low temperatures. When powered,the magnetoresistive Wheatstone bridge converts the magnetic field in the sensitivity direction into a voltage output. In addition to the magnetoresistive bridge circuit,the sensor also contains a magnetically coupled initialization coil. This multi-dimensional patented feature allows for proper magnetic domain alignment,even in uncontrolled environments where large magnetic field exposure or temperature changes are unavoidable,enabling a sensor that can provide stable low hysteresis and low bias output. TMR9112 package: LGA (6mm X 6 mm X 0.75 mm).
