EVAL-CN0371-SDPZ, Low Power LVDT Signal Conditioner Evaluation Board with Synchronous Demodulation
参考設計 著者: Analog Devices
EVAL-CN0371-SDPZ, Evaluation Board is a complete linear variable differential transformer (LVDT) signal conditioning circuit that can accurately measure linear position or linear displacement from a mechanical reference. Synchronous demodulation in the analog domain is used to extract the position information and provides immunity to external noise. A 24-bit analog-to-digital converter (ADC) digitizes the position output for high accuracy. LVDTs utilize electromagnetic coupling between the movable core and the coil assembly. This contactless (and hence frictionless) operation is a primary reason for why they are widely used in aerospace, process controls, robotics, nuclear, chemical plants, hydraulics, power turbines, and other applications where operating environments can be hostile and long life and high reliability are required
