Product Overview

AD598 is a complete, monolithic linear variable differential transformer (LVDT) signal conditioning subsystem. It is used in conjunction with LVDTs to convert transducer mechanical position to a unipolar or bipolar DC voltage with a high degree 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 AD598 converts the raw LVDT secondary output to a scaled dc signal. The device can also be used with RVDT transducers. The AD598 contains a low distortion sine wave oscillator to drive the LVDT primary. The LVDT secondary output consists of two sine waves that drive the AD598 directly. The AD598 operates upon the two signals, dividing their difference by their sum, producing a scaled unipolar or bipolar DC output.
  • Single chip solution, contains internal oscillator and voltage reference, no adjustments required
  • Insensitive to transducer null voltage
  • Insensitive to primary to secondary phase shifts
  • DC output proportional to position
  • 20Hz to 20KHz frequency range and unipolar or bipolar output
  • Single or dual supply operation, operate a remote LVDT at up to 300feet, also interface to an RVDT
  • Position output can drive up to 1000feet of cable
  • ±500ppm of FS nonlinearity, ±11V min O/P voltage, ±50ppm/°C of FS max gain drift and offset drift
  • 20 lead ceramic DIP package
  • Operating temperature range from -40°C to 85°C
