Si720x Switch/Latch Hall Effect MagneticPosition Sensor Data SheetThe Si7201/2/3/4/5/6 family of Hall effect magnetic sensorsswitches and latches from Silicon Labs combines a chopper-stabi-lized Hall element with a low-noise analog amplifier, 13-bit analog-to-digital converter, and a flexible comparator circuit. LeveragingSilicon Labs' proven CMOS design techniques, the Si720x familyincorporates digital signal processing to provide precise compen-sation for temperature and offset drift.Compared with existing Hall effect sensors, the Si720x family offers industry-leadingsensitivity, which enables use with larger air gaps and smaller magnets. For battery-powered applications, the Si720x family offers very low power consumption to improveoperating life.The Si720x devices are offered in 3-pin SOT23, 5-pin SOT23, and TO-92 packages,with power, ground, a single output pin that goes high or low as the magnetic field in-creases, and with the 5-pin parts a disable(sleep) pin, and a tamper output pin. With thethree-pin package, tamper indication is by the pin going back to its zero field level athigh magnetic field.Applications:FEATURES• High-Sensitivity Hall Effect Sensor• Maximum BOP operating point/minimumfield strength of
