General Description

SS657 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 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.
