ing the direction of rotation of a ring magnet. This transducer provides
speed, direction, and magnet pole count. This device eliminates the ma-

applications, namely maintaining accurate mechanical location between
the two active Hall elements. Here, the two Hall elements are photo-
lithographically aligned to better than 1
渭m,
as contrasted with 100
渭m
or worse mechanical location tolerance when manufactured discretely.
This highly sensitive, temperature-stable, magnetic transducer is ideal
for use in digital-encoder systems in the harsh environments of auto-
motive or industrial applications. The A3422xKA is a high-sensitivity
device optimized for use with high-density magnets.
The A3422xKA monolithic integrated circuit contains two inde-
pendent Hall-effect bipolar switches whose digital outputs are internally
coupled to CMOS logic circuitry that decodes signal speed and direc-
tion. Extremely low-drift BiCMOS circuitry is used for the ampli鏗乪rs
to ensure symmetry between the two switches so that signal quadrature
can be maintained. An on-chip voltage regulator allows the use of this
device from a 4.5 V to 18 V supply. The outputs are standard open-col-
lector outputs.
Two operating temperature ranges are provided; suf鏗亁 鈥楨鈥撯€?is for

petitive solution to magnetic sensing in harsh environments.
