Si7210 I C Hall Effect Magnetic Position

and Temperature Sensor Data Sheet

The Si7210 family of Hall effect magnetic sensors from Silicon Labs combines a chop-

per-stabilized Hall element with a low-noise analog amplifier, 13-bit analog-to-digital

converter, and an I²C interface. Leveraging Silicon Labs' proven CMOS design techni-

FEATURES

• High-Sensitivity Hall Effect Sensor

ques, the Si7210 family incorporates digital signal processing to provide precise com-

pensation for temperature and offset drift.

• Adjustable Full Scale (Standard

Offerings are ±20mT and ±200 mT Full

Scale)

Compared with existing Hall effect sensors, the Si7210 family offers industry-leading

sensitivity, which enables use with larger air gaps and smaller magnets. The integrated

13-bit high-precision ADC delivers high output linearity with very low noise for the high-

est measurement accuracy. For battery-powered applications, the Si7210 family offers

very low power consumption to improve operating life.

• Integrated Digital Signal Processing for

Temperature and Offset Drift

Compensation

• High-Precision 13-bit Signal Path

• Output Bandwidth up to 20 kHz

• Sensitivity Drift < ±5% over 0-70 °C

The Si7210 family supports a bidirectional I²C interface which provides full configurabili-

ty of the Hall effect sensor operate and release points. At any time, the 13-bit magnetic

field strength can be read through the I²C interface.
