A1318 and A1319

Linear Hall-Effect Sensor ICs with Analog Output

Allegro MicroSystems, LLC

The Allegro A1318 and A1319 linear Hall-effect sensor ICs have been designed specifically to meet both requirements. These temperature-stable devices are available in a miniature surface mount package (SOT23-W). The accuracy of each device is enhanced via end-of-line optimization. Each device features non-volatile 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 A1318 and A1319 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.
