    APPLICATIONS

    Most of the applications for the AD598 can also be imple mented with the AD698. Please refer to the applications written for the AD598 for a detailed explanation.

    See AD598 data sheet for:

    – Proving Ring-Weigh Scale

    – Synchronous Operation of Multiple LVDTs

    – High Resolution Position-to-Frequency Circuit

    This circuit can be used for resistive bridges such as strain gages, or for inductive or capacitive bridges that are commonly used for pressure or flow sensors. The low level signal outputs of these sensors are susceptible to noise and interference and are good candidates for ac signal processing techniques.


    DESCRIPTION

    The AD698 is a complete, monolithic Linear Variable Differen tial Transformer (LVDT) signal conditioning subsystem. It is used in conjunction with LVDTs to convert transducer mechan ical position to a unipolar or bipolar dc voltage with a high de gree 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 AD698 converts the raw LVDT output to a scaled dc signal. The device will operate with half-bridge LVDTs, LVDTs connected in the series op posed configuration (4-wire), and RVDTs.

    The AD698 contains a low distortion sine wave oscillator to drive the LVDT primary. Two synchronous demodulation channels of the AD698 are used to detect primary and second ary amplitude. The part divides the output of the secondary by the amplitude of the primary and multiplies by a scale factor. This eliminates scale factor errors due to drift in the amplitude of the primary drive, improving temperature performance and stability.

    The AD698 uses a unique ratiometric architecture to eliminate several of the disadvantages associated with traditional ap proaches to LVDT interfacing. The benefits of this new cir cuit are: no adjustments are necessary; temperature stability is improved; and transducer interchangeability is improved.
