Description
New applications for linear output Hall effect sensors, such as displacement, angular position, and current measurement, require high accuracy in conjunction with small package size. The Allegro® A138x family of programmable linear Halleffect sensors 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.
