A1324/5/6 Linear Hall Effect Sensor with Analogue Output, Allegra Microsystems The Allegro A1324/5/6 linear Hall-effect sensor ICs provide a voltage output that is proportional to the applied magnetic field. Featuring a quiescent voltage output of 50% of the supply voltage and are pre-programmed to sensitivities of 5.0 mV/g, 3.125 mV/g, and 2.5 mV/g, respectively. Each IC integrates a Hall element, temperature-compensating circuitry, a small-signal high-gain amplifier, a clamped low-impedance output stage, and a proprietary dynamic offset cancellation technique. Available in a 3-pin ultra-mini SIP package, and a 3-pin surface mount SOT-23 package. Temperature-stable quiescent output voltage and sensitivity Output voltage proportional to magnetic flux density Low-noise output increases accuracy Precise recoverability after temperature cycling Ratiometric rail-to-rail output Wide ambient temperature range: –40°C to 150°C Immune to mechanical stress Solid-state reliability Enhanced EMC performance for stringent automotive applications ### 霍尔效应传感器，Allegro Microsystems
