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.
