The application specific paper describes a design approach for digital magnetic sensors Practical realizations are based on the Universal Frequency-to-Digital Converter (UFDC-1). By eliminating the need for ADC, the frequency- or duty-cycle-to-digital conversion schemes reduce the systems complexity. The results of such design approach are high-performance digital magnetic sensors with truly digital output (RS-232 interface) or bus output (SPI or I 2 C) at significant reduction of production cost, time-to-market and simplification of the design process. Practical examples of direct interfacing of duty-cycle and frequency output magnetic sensors to the UFDC-1 are given.
