Description
put, 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 has an operating
temperature range of -40 °C to 150 °C appropriate for commercial, consumer and industrial
environments.
SS4825 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 integrated circuitry features low noise out-
