Hall effect sensor, SI7201-B-01-FV, Silicon Laboratories

The SI7201-B-01-FV is a hall effect magnetic sensor that combines a chopper-stabilized hall element with a low-noise analog amplifier, 13-bit analogto-digital converter, and a flexible comparator circuit. This product offers industry-leading sensitivity, which enables use with larger air gaps and smaller magnets.

Features

• High sensitivity hall effect sensor
• Selectable sensitivity, hysteresis, output polarity and sample rate
• Omnipolar or unipolar operation
• Open-drain output
• Digital high/low output

Applications

• Control knobs and selector switches
• General-purpose mechanical position sensing
• Camera image stabilization, zoom, and autofocus
• Replacement of reed switches in consumer, and security applications
• Fluid level sensing
