High Precision Programmable Linear Hall Effect Sensor IC with EEPROM, Analog Output, and Advanced Output Linearization

A1340

Advanced 32-segment output linearization functionality enables high output accuracy and linearity in the presence of non-linear input magnetic fields
Customer adjustable sensitivity and offset, bandwidth, output clamps, and 1st and 2nd order temperature compensation
Simultaneous programming of all parameters for accurate and efficient system optimization
Factory trimmed magnetic input range (coarse sensitivity) and signal offset
Sensitivity temperature coefficient and magnetic offset drift preset at Allegro, for maximum device accuracy without requiring customer temperature testing
Temperature-stable, mechanical stress immune, and extremely low noise device output via proprietary four-phase chopper stabilization and differential circuit design techniques
Diagnostics for open circuit and undervoltage
Wide ambient temperature range: –40°C to 150°C
Operates with 4.5 to 5.5 V supply voltage
