Si720x & Si721x Hall Effect Magnetic Sensors

Silicon Labs Si720x and Si721x Hall Effect Magnetic Position Sensors combine a chopper-stabilized Hall element with a low-noise analog amplifier and 13-bit analog to digital converter. The sensors have proven CMOS design techniques and incorporate digital signal processing for precise temperature and offset drift compensation. The Si720x and Si721x enable use with larger air gaps and smaller magnets and are AEC-Q100 qualified for automotive applications.
