Description
New applications for linear output Hall effect sensing, such
as displacement, angular position, and current measurement,
require high accuracy in conjunction with small package size.
TheAllegroA138x family of programmable linear Hall effect
sensor ICs was designed specifically to achieve both goals.
These temperature-stable devices are available in a miniature
surface mount package (SOT23-W) and an ultramini through-
hole single-in-line package. The accuracy of these devices is
enhanced via programmability on the output pin for end-of-line
optimization without the added complexity and cost of a fully
programmable device.
These ratiometric Hall effect devices provide a voltage output
that is proportional to the applied magnetic field. Both the
quiescent voltage output and magnetic sensitivity are user-
adjustable. The quiescent voltage output can be set around
50% of the supply voltage, and the sensitivity adjusted between
2 mV/G and 9 mV/G over the device family. Programming
selections also exist for output polarity and temperature
compensation. The features of this linear family make it ideal
for high accuracy requirements of automotive and industrial
applications, and performance is guaranteed over an extended
temperature range, –40°C to 150°C.
