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。
PRODUCT DESCRIPTION
The AD698 is a complete, monolithic Linear Variable Differen-
tial Transformer (LVDT) signal conditioning subsystem. It is
used in conjunction with LVDTs to convert transducer mechan-
ical position to a unipolar or bipolar dc voltage with a high de-
gree 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 AD698 converts the
raw LVDT output to a scaled dc signal. The device will operate
with half-bridge LVDTs, LVDTs connected in the series op-
posed configuration (4-wire), and RVDTs. (2018-08-04, C51, 205KB, 下载1次)
