本电路采用AD698 LVDT信号调理器,包含一个正弦波振荡器和一个功率放大器,用于产生驱动原边LVDT的激励信号。AD698还可将副边输出转换为直流电压。AD8615轨到轨放大器缓冲AD698的输出,并驱动低功耗12位逐次逼近型模数转换器(ADC)。系统动态范围为82 dB,带宽为250 Hz,非常适合精密工业位置和计量应用。
This circuit uses the AD698 LVDT signal conditioner, which includes a sine wave oscillator and a power amplifier to generate the excitation signal that drives the primary LVDT. The AD698 also converts the secondary output to a DC voltage. The AD8615 rail-to-rail amplifier buffers the output of the AD698 and drives a low-power, 12-bit successive approximation analog-to-digital converter (ADC). With a system dynamic range of 82 dB and a bandwidth of 250 Hz, it is ideal for precision industrial location and metrology applications. (2018-08-15, C51, 452KB, 下载17次)
