概述：     

       The HS49E linear Hall-effect sensor ICs are small, versatile devices that are operated by the magnetic field from a permanent magnet or an electromagnet. The output signal level is determined by the magnetic field strength applied to the sensitive surface of the device, varying proportional with the magnetic field strength.

       The HS49E features a low noise output and no longer requires external filtering.It also includes a thin-film resistance, which can improve the temperature stability and accuracy.For various commercial and consumer electronics applications.
