The AD598SD/883B is a complete, monolithic Linear Variable Differential Transformer (LVDT) signal conditioning subsystem from Analog Devices. It is processed to MIL-STD-883B for the military temperature range of -55°C to 125°C. The device converts mechanical position from an LVDT transducer to a scaled unipolar or bipolar DC voltage with high 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 AD598 uses a unique ratiometric architecture that eliminates several disadvantages associated with traditional LVDT interfacing. No adjustments are necessary, transformer null voltage and primary to secondary phase shift do not affect system accuracy, temperature stability is improved, and transducer interchangeability is improved.
The AD598SD/883B is supplied in a 20-pin ceramic DIP (20-CDIP) package with through hole mounting, suitable for demanding military and aerospace applications.
