◼ General Description
The OCH1931 is a small, versatile linear
Hall-effect device that is operated by the magnetic field
from a permanent magnet or an electromagnet .The
linear 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 85 °C appropriate for
commercial, consumer and industrial environments.
