Transfer Characteristics (VCC=5V)
When there ouside magnetic field (B=0GS), quiescent output voltage one-half supply voltage general. south magnetic pole approches front face (the side with marking Halleffect sensor, circuit will drive output voltage higher. Contrary, north magnetic pole will drive output voltage lower. variations voltage level down symmetrical. Greatest magnetic sensitivity obtained with supply voltage cost increased supply current slight loss output symmetry. recommended work such condition unless output voltage magnitude main issue. output signal capacitively coupled amplifier boosting further changing frequency magnetic field high.
