Product Overview

The AD598AD is a Monolithic Linear Variable Differential Transformer (LVDT) Signal Conditioner 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. It contains a low distortion sine wave oscillator to drive the LVDT primary. The LVDT secondary output consists of two sine waves that drive the conditioner directly. The AD598 operates upon the two signals, dividing their difference by their sum, producing a scaled unipolar or bipolar DC output. The AD598 uses unique ratiometric architecture (patent pending) to eliminate several of the disadvantages associated with traditional approaches to LVDT interfacing.
  • 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
  • Outstanding performance
  • 0.05% of FS maximum linearity
  • 611V Minimum output voltage
  • 50ppm/8C of FS maximum gain drift
  • 50ppm/8C of FS maximum offset drift
