MH4803单极线性霍尔传感器应用:磁轴键盘/电流感测/位置感应

MH4803 is a low-power, wide linear range, wide voltage, and wide temperaturerangelinear Hall sensor specifically optimized for unipolar applications of magnetic axis keyboard. The zero-point output voltage (VDD = 3.3V, no magnetic field) is set at 2.18V. Its output

voltage changes proportionally with the intensity of the sensed magnetic field, and its linearoutput voltage range varies with the power supply voltage.The linear Hall sensor has awideoperating temperature range of -40℃ to +85℃, appropriate for commercial, consumer, andindustrial environments. The high sensitivity of Hall-effect sensor accurately tracks extremely weak changesinmagnetic flux density. The linear output voltage is set by the supply voltage and is proportional

to the variation of the magnetic flux density. Operating voltage range is 2.7 volts to 8.0volts. Features and Benefits
