AD698 - Universal LVDT Signal Conditioner

General Description

PRODUCT HIGHLIGHTS The AD698 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.
