Si721x Field Output Hall Effect Magnetic Position Sensors Data Sheet The Si7211/2/3/4/5/6/7 family of Hall-effect sensors from Silicon Labs combines a chopper-stabilized Hall element with a low-noise analog amplifier, 13-bit analog to digital converter. After A/D conversion the magnetic field data is available in analog. PWM or SENT format (depending on the part number). Leveraging Silicon Labs' proven CMOS design techniques, the Si721x family incorporates digital signal processing to provide precise compensation for temperature and offset drift. Compared with existing Hall-effect sensors, the Si721x family offers industry-leading sensitivity and low noise, which enables use with larger air gaps and smaller magnets.
