New applications for linear output Hall-effect devices, such
as displacement, angular position, and current measurement,
require high accuracy in conjunction with small package size.
The Allegro™ A1324, A1325, and A1326 linear Hall-effect
sensor ICs are designed specifically to achieve both goals. This
temperature-stable device is available in a miniature surface
mount package (SOT23W) and an ultra-mini through-hole
single in-line package.
These ratiometric Hall effect sensor ICs provide a voltage
output that is proportional to the applied magnetic field. They
feature a quiescent voltage output of 50% of the supply voltage.
The A1324/25/26 feature factory programmed sensitivities of
5.0 mV/G, 3.125 mV/G, and 2.5 mV/G, respectively.
