Our one customer want to apply AD698 in RVDT Signal Conditioning. But in AD698's datasheet, there only are the LVDT typical circuits. So would you please give us some circuits about RVDT Application?
I don't have any circuit diagrams specific to an RVDT application. RVDTs would generally have the same circuit diagram as a 5 wire LVDT so Fig 7 or 12 in the AD598 datasheet would be suitable for RVDT application. You mentioned that your customer was interested in using the AD698. This part is not suited for 5-wire LVDTs, or in this case RVDTs. That part is targeted at 4 or 3 wire LVDTs and so has a different transfer function. The transfer function of the AD598 (A-B/A+B) is better suited to RVDT applications. I would suggest that the AD598 be used in the application.
