CMOS High Sensitivity Micropower
YHM148                                             Hall Switch

Installation Comments
Consider temperature coefficients of Hall IC and magnetic, as well as air gap and life time
variations. Observe temperature limits during wave soldering.

T*ical Application

Eastera's pole-independent sensing technique
allows for operation with either a north pole or
south pole magnet orientation, enhancing the
manufacturability of the device. The
state-of-the-art technology provides the same
output polarity for either pole face.
It is strongly recommended that an external
b** capacitor be connected (in close proximity
to the Hall sensor) between the supply and ground
of the device to reduce both external noise and
noise generated by the chopper-stabilization
technique. This is especially true due to the
relatively high impedance of battery supplies.
