Product Summary

The AD598AD 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. All circuit functions are included on the chip. With the addition of a few external passive components to set frequency and gain, the AD598AD converts the raw LVDT secondary output to a scaled dc signal. The device can also be used with RVDT transducers. The AD598AD contains a low distortion sine wave oscillator to drive the LVDT primary. The LVDT secondary output consists of two sine waves that drive the AD598AD directly. The AD598AD operates upon the two signals, dividing their difference by their sum, producing a scaled unipolar or bipolar dc output.
