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.
