♠ Linear Hall-Effect Sensor ICs with Analog Output Available in a Miniature, Low-Profile Surface-Mount Package
New applications for linear output Hall-effect sensors, such as displacement and angular position, require higher accuracy and smaller package sizes. The Allegro A1308 and A1309 linear Hall-effect sensor ICs have been designed specifically to meet both requirements. These temperature-stable devices are available in both surface-mount and through-hole packages.
The accuracy of each device is enhanced via end-of-line optimization. Each device features nonvolatile memory to optimize device sensitivity and the quiescent voltage output (QVO: output in the absence of a magnetic field) for a given application or circuit. This A1308 and A1309 optimized performance is sustained across the full operating temperature range by programming the temperature coefficient for both sensitivity and QVO at Allegro end-of-line test.
These ratiometric Hall-effect sensor ICs provide a voltage output that is proportional to the applied magnetic field. The quiescent voltage output is adjusted around 50% of the supply voltage. The features of these linear devices make them ideal for use in automotive and industrial applications requiring high accuracy, and they operate across an extended temperature range, –40°C to 150°C (SOT-23W and SIP -L temperature range) or –40°C to 125°C (SIP -K temperature range).
Each BiCMOS monolithic circuit integrates a Hall element, temperature-compensating circuitry to reduce the intrinsic
