The AD598JR 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.The AD598JR uses a unique ratiometric architecture (patent pending to eliminate several of the disadvantages associated with traditional approaches to LVDT interfacing.

The absolute maximum ratings of the AD598JR can be summarized as:(1):the parameter is total supply voltage +VS to –VS,the rating is +36,the unit is V;(2):the parameter is storage temperature range R package,the rating is –65 to +150,the unit is ℃;(3):the parameter is operating temperature range,the rating is 0 to +70,the unit is ℃;(4):the parameter is lead temperature range (soldering 60 sec),the rating is +300,the unit is ℃;(5):the parameter is power dissipation up to +65℃,the rating is 1.2 ,the unit is W;(6):the derates above +65℃,the rating is 12 ,the unit is mW/℃.
