SENSOR
DESCRIPTION
UTC
UHS49
Linear Hall-effect sensor is small, versatile linear
Hall-effect device that is operated by the magnetic field from a
permanent magnet or an electromagnet. The linear sourcing output
voltage is set by the supply voltage and varies in proportion to the
strength of the magnetic field. The IC features low noise output,
which makes it unnecessary to use external filtering. It also
includes thin film resistors to provide increased temperature
stability and accuracy. The linear Hall sensor can be used for Motor
control, Magnetic code reading, Ferrous metal detector，Current
sensing and Position sensing .
