MH49A3, sensitivity adjustable of linear Hall-effect sensor, is composed of Hall sensor,
linear amplifier and Totem-Pole output stage. It features low noise output, which use an
external capacitance. It also can provide increased temperature stability and accuracy. The
linear Hall sensor has a wide operating temperature range of -40℃to +125℃, appropriate for
commercial, consumer, and industrial environments.
The high sensitivity of Hall-effect sensor accurately tracks extremely weak changes in
magnetic flux density. The linear sourcing output voltage is set by the supply voltage and in
proportion of vary of the magnetic flux density. That is proportional to the applied magnetics
and features a null voltage output of half of the applied voltage.
The SD,SM package is an ultra-mini SMD in SMT process.
