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.

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020D for
MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).
ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and advise
customers to obtain the latest version of relevant information to verify before placing orders.
