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. Principle features include dynamic offset drift cancellation and a built-in temperature sensor. Designed for single +5 volt supply operation, the AD22151 achieves low drift offset and gain operation over –40°C to +150°C. Temperature compensation can accommodate a number of magnetic materials commonly utilized in economic position sensor assemblies. The transducer may be configured ……
