General Description

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.
