The AD698 is a complete, monolithic Linear Variable Differential Transformer (LVDT) signal conditioning subsystem. It is used in conjunction with LVDTs to convert transducer mechanical position to a unipolar or bipolar dc voltage with a high degree of accuracy and repeatability.
The AD698 is a monolithic LVDT signal‑conditioning subsystem that converts mechanical position to a precise unipolar or bipolar DC voltage. It integrates an oscillator, voltage reference and demodulation circuitry, requiring only a few external passive components.
The handbook provides a complete description of the device, including functional block diagrams, detailed electrical specifications, theory of operation, connection diagrams for dual‑ and single‑supply configurations, design procedures, and ordering information.
