-[[http://www.analog.com/CN0301|CN-0301]] is a linear variable differential transformer (LVDT) signal conditioning circuit.  The system converts the output of the LVDT sensor to a unipolar DC voltage and drives the inputs of a successive approximation analog-to-digital converter (ADC).+[[adi>CN0301|CN-0301]] is a linear variable differential transformer (LVDT) signal conditioning circuit.  The system converts the output of the LVDT sensor to a unipolar DC voltage and drives the inputs of a successive approximation analog-to-digital converter (ADC).
  
 This circuit uses a single chip solution that drives the excitation signal of the primary side of the LVDT and converts the secondary side.  The complete system uses a 12-bit ADC resulting in a dynamic range of 82dB at a standard LVDT bandwidth of 250Hz.  (The term bandwidth used in this case is referring to a sinusoidally varying mechanical position and can be easily configured to meet wider bandwidth applications by configuring a few external passive components.)   This circuit uses a single chip solution that drives the excitation signal of the primary side of the LVDT and converts the secondary side.  The complete system uses a 12-bit ADC resulting in a dynamic range of 82dB at a standard LVDT bandwidth of 250Hz.  (The term bandwidth used in this case is referring to a sinusoidally varying mechanical position and can be easily configured to meet wider bandwidth applications by configuring a few external passive components.)
