Description
SS4833 Linear Hall-effect sensor is a small,
versatile linear Hall-effect device that is operat-
ed 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 mag-
netic field. Specifically, when SS4833 is in the
zero magnetic field conditions, the output volt-
age is half of the supply voltage. When south
poles approach the SS4833 marking surface, the
output voltage will increase linearly with the
magnetic field strength; on the other hand, north
pole will cause output voltage decreases linearly
with the increase in magnetic field strength. The
integrated circuitry features low noise output,
which makes it unnecessary to use external fil-
tering. It also includes thin film resistors to pro-
vide increased temperature stability and accura-
cy. The linear Hall sensor has an operating tem-
perature range of -40 °C to 150 °C appropriate
for commercial, consumer and industrial envi-
ronments.
