磁科幻场传感器 Magnetic field sensor
Overview
The is a sensitive magnetic field sensor, employing the magneto-resistive effect of thin film permalloy. The sensor contains two galvanically separated Wheatstone bridges, which enclose an angle of 45 degrees.
A rotating magnetic field strength > 40 kA/m recommended field strength > 100 kA/m in the surface parallel to the chip x-y plane will deliver two independent sinusoidal output signals, one following a cos2α and the second following a sin2α function.
The sensor can be operated at any frequency between DC and 1 MHz.
