In order to provide system designers a new cost-effective and easy alternative to assured precision temperature measurement, this reference design discusses the new tiny 2-pin digital output IC temperature sensor with single wire pulse count interface that enhances reliability and greatly simplifies the design of galvanic isolation architecture for sending both power and unidirectional data through same low profile transformer and remote operation. In addition, with fewer error sources, computation of error budget is easier. Cost budgets, accuracy, size and simplicity of interfacing with other circuit elements are main factors in selecting a sensor to do a job and this reference design system tremendously helps in meeting all these requirements.
