A1381, A1382, A1383, and A1384  
Programmable Linear Hall Effect Sensors with Analog Output  
Available in a Miniature Thin Profile Surface Mount Package  
Features and Benefits  
Description  
Customer programmable offset, sensitivity, sensitivity  
temperature coefficient, and polarity  
Programmability at end-of-line  
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 Hall  
effect 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  
enhancedviaprogrammabilityontheoutputpinforend-of-line  
optimization without the added complexity and cost of a fully  
programmable device.  
Ratiometric sensitivity, quiescent voltage output, and  
clamps for interfacing with application DAC  
Temperature-stable quiescent voltage output  
and sensitivity  
Precise recoverability after temperature cycling  
Output voltage clamps provide short circuit  
diagnostic capabilities  
Wide ambient temperature range: –40°C to 150°C  
Immune to mechanical stress  
These ratiometric Hall effect sensors 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%ofthesupplyvoltage,andthesensitivityadjustedbetween  
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.
