AD22151YRZ (ANALOG DEVICES)

The AD22151YRZ is a Linear Output Magnetic Field Sensor designed for single 5V supply operation achieving low drift offset. The sensor output is a voltage proportional to a magnetic field applied perpendicularly to the package top surface. The sensor combines integrated bulk hall cell technology and instrumentation circuitry to minimize temperature related drifts associated with silicon hall cell characteristics. The architecture maximizes the advantages of a monolithic implementation while allowing sufficient versatility to meet varied application requirements with a minimum number of components. Principal features include dynamic offset drift cancellation and a built-in temperature sensor. The transducer can be configured for specific signal gains to meet various application requirements. Output voltage can be adjusted from fully bipolar (reversible) field operation to fully unipolar field sensing.
