Programmable Linear Hall Sensor
For Industrial Use
1
1.1
• High linear and ratiometric push-pull rail-to-rail output
• 20 bit Digital Signal Processing
• Digital temperature compensation
• 12 bit overall resolution
• Operates from -40°C up to 120°C
• Low drift of output signal over temperature and lifetime
• Programmable parameters stored in redundant EEPROM (single bit error correction):
• Re-programmable until memory lock
• Single supply voltage 4.5 - 5.5 V (4 - 7 V in extended range)
• Continuous measurement ranges between -200 mT and +200 mT
• Slim 3 pin package (Green)
• Reverse polarity and overvoltage protection for all pins
• Output short circuit protection
• On board diagnostics (wire breakage detection, under voltage, over voltage)
• Digital readout of internal temperature and magnetic field values in calibration mode.
• Individual programming and operation of multiple sensors with common power supply
• Two point calibration of magnetic transfer function
• Precise calibration without iteration steps
• High immunity against mechanical stress, EMC, ESD
