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. Designed for single 5 V 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 can be configured for specific signal gains to meet various application requirements.
