Many of today’s embedded systems incorporate multiple analog sensors that make devices more intelligent, and provide users with an array of information resulting in improved efficiency or added convenience. The Analog Front End (AFE), allowing the connection of the sensor to the digital world of the MCU, is often an assumed “burden” in designing sensor interface circuits. However, the latest concept in a configurable AFE, integrated into a single package, is helping systems designers overcome sensor integration challenges associated with tuning and sensor drift, thereby reducing time to market. The following embedded discussion examines how the versatility of such a technology allows the designer to tune and debug AFE characteristics on the fly, automate trimming and adjust for sensor drift, and add scalability to support multiple sensor types with a single platform.
