Si721x Series Hall Effect Field Output Sensors


A range of Hall-effect magnetic sensors from Silicon Labs featuring chopper-stabilized Hall elements, low-noise amplifiers and 13-bit ADCs which provide a linear outputs proportional to magnetic field strength. The Si721x series are available with analogue, PWM or SENT (Single Edge Nibble Transmission) outputs. Typical applications include mechanical position sensing in consumer, industrial and automotive applications, camera image stabilization, zoom, and autofocus functions, sensing of control knobs and selector switches.


• Industry-leading sensitivity allows use with larger air gaps and smaller magnets
• Precise compensation for temperature and offset drift.
• Low power consumption to improve operating life in battery powered applications
• Low voltage (1.7-5.5V) and High voltage (3.3-26.5V) versions
• Compact 3 or 5-pin SOT23 package
• AEC-Q100 Qualified for automotive applications


The Si721x 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). 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.
