EVAL-CN0301-SDPZ

The EVAL-CN0301-SDPZ is an universal linear variable differential transformer (LVDT) signal conditioning circuit evaluation board. This circuit uses the AD698 LVDT signal conditioner that contains a sine wave oscillator and a power amplifier to generate the excitation signals that drive the primary side of the LVDT. This circuit also uses AD8615 precision, 20MHz, CMOS, single RRIO operational amplifier and AD7992 two channel, 12bit ADC with I2C compatible Interface. This circuit can accurately measure linear displacement (position). The LVDT is a highly reliable sensor because the magnetic core can move without friction and does not touch the inside of the tube. Therefore, LVDTs are suitable for flight control feedback systems, position feedback in servomechanisms, automated measurement in machine tools and many other industrial and scientific electromechanical applications where long term reliability is important.
