The Si7210 family of Hall effect magnetic sensors from Silicon Labs offers a high-sensitivity sensor with an integrated 13-bit analog-to-digital converter and an I2C interface. This sensor is designed for precise compensation of temperature and offset drift through digital signal processing. It provides high output linearity with low noise for accurate measurements.
Key features include adjustable full-scale options, an output bandwidth up to 20 kHz, and a sensitivity drift of less than ±5% over the 0-70 °C temperature range. The device supports a bidirectional I2C interface for full configurability of operate and release points, and the magnetic field strength can be read at any time. It also includes an integrated temperature sensor with ±1°C accuracy, accessible via I2C.
This Hall effect sensor is available in industry-standard packaging, specifically a surface-mount SOT23-5 and a 1.4 x 1.6 mm 8-pin DFN package. Its low power consumption, with a sleep mode current of only 50 nA, makes it suitable for battery-powered applications. The wide operating voltage range of 1.7 to 5.5 V and operating temperature range of -40°C to 125°C (TA) ensure versatility in various environments.
Applications for the Si7210 family include mechanical position sensing in consumer and industrial applications, replacement of reed switches, fluid level measurement, speed sensing, utility meters, and control knobs and selector switches.
