General Description
2 2 GND
SS657 Linear Hall-effect sensor is small, versatile
linear Hall-effect device that is operated by the mag-
netic field from a permanent magnet or an electro-
magnet. 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 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 has an operating temperature range of
-40 °C to 150 °C appropriate for commercial, consumer and industrial environments.
