DESCRIPTION

· The Si721x family from Silicon Labs features Hall-effect sensors with chopper-stabilized Hall elements and low-noise analog amplifiers.
· Includes a 13-bit ADC for magnetic field data conversion, available in analog, PWM, or SENT formats.
· Utilizes CMOS design for digital signal processing to compensate for temperature and offset drift.
· Available in 3-pin SOT23 or TO92 packages, with options for 5-pin SOT23 and 8-pin DFN packages for additional functionalities like sleep mode and self-test.

FEATURES

· High sensitivity and low noise for effective use with larger air gaps and smaller magnets.
· Integrated DSP for precise temperature and offset drift compensation.
· Low sleep current consumption of 50 nA.
· Configurable sensitivity, output polarity, and sample rate.
· Wide power supply voltage range from 1.7V to 26.5V.
· Multiple output options including analog, PWM, and SENT.
· Available in industry-standard packages like SOT-23, TO92, and DFN.

APPLICATIONS
