Reference Design Spotlight on Linear and Angular Position and Velocity
Sensing and measurement of linear and angular position and velocity is required in a variety of industrial, motor control, medical, avionics, and other applications. The most popular sensor types used to perform these functions are electronic and electromechanical such as MR (magneto resistive), resolvers, MEMS (microelectromechanical systems) accelerometers, LVDTs (linear variable differential transformers), and ultrasonic. Signal conditioning circuitry (typically a combination of ADC, voltage reference, input drive amplifier, instrumentation amplifier, multiplexer, and/or power supply) converts sensor output into a digital format that can be interpreted and processed. In addition to the choice of sensor and signal conditioning components selected for the final design, achieving required performance levels depends on giving careful attention to layout, grounding, and decoupling techniques.
Circuits from the Lab reference designs featured in the table below enable quick integration and evaluation.
