The APX9122, integrated circuit, is an ultra-sensitive, pole
independent Hall-effect switch with a latched digital output.
A 1.6 volt to 3.5 volt operation and an unique clocking
scheme reduce the average operating power
requirements, either a north or a south pole of sufficient
flux will turn the output on; in the absence of a magnetic
field, the output is off. The polarity independence and
minimal power requirement allow this device to be easily
replaced reed switch for superior for signal conditioning.
Advanced CMOS processing is used to take advantage of
low-voltage and low-power requirements, SOT-23 pack-
age provides an optimized package for most applications.
