Sensor Interface Signal Chains

When interfacing with the real world, sensors are required to measure physical quantities such as position and temperature. These sensors produce signals that are often small and noisy, requiring high performance amplifiers and converters to measure, condition and process them. Analog Devices Sensor Interface signal chains offer a variety of solutions from the most comprehensive portfolio of precision building block products to system-level solutions, enabling designers to achieve the desired performance from their sensors. In addition, Analog Devices Circuits from the Lab® (CftL) reference designs are engineered and tested for time-saving evaluation and easy integration. Explore the interactive sensor-interface signal chains on this page to find the right solutions for your designs.
