Product Information

The Si7211/2/3/4/5/6 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. 

For automotive applications, the Si720x family is AEC-Q100 qualified. In the simplest case, the Si721x devices are offered in a 3 pin package with power, ground, and a single output pin that is signal corresponding to the magnetic field in analog, PWM, or SENT format. 

The Si721x devices are also offered in a 5 pin SOT23 and 8 pin DFN packages where the additional pins can be used for sleep mode (DIS) or to activate an on-chip coil for built in self-test (BISTb).
