- With the addition of a few external passive components to set frequency and gain, the AD698 converts the raw LVDT output to a scaled dc signal. The device will operate with half-bridge LVDTs, LVDTs connected in the series opposed configuration (4-wire), and RVDTs. The AD698 contains a low distortion sine wave oscillator to drive the LVDT primary.

AD698是一款完整的单芯片线性可变差分变压器 (LVDT)信号调理子系统,结合LVDT使用,能够以较高精度和可重复性将传感器机械位置转换为单极性或双极性直流电压。. 所有电路功能均集成于片内。. 只要增加几个外部无源元件以设置频率和增益,AD698就能将原始LVDT ...
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 uses a unique ratiometric architecture to eliminate several of the disadvantages associated with traditional approaches to LVDT interfacing. The benefits of this new circuit are: no adjustments are necessary; temperature stability is improved; and transducer interchangeability is improved.
