A high-precision, three-axis accelerometric signal

Leti has designed an addressing electronic circuit offering accuracy to within a thousandth of the full dynamic scale. The circuit’s accuracy was measured in tests conducted by Thales Avionics. While single-axis sensors commonly offer comparable degrees of accuracy—especially in aerospace and defense applications—this Leti-designed circuit marks the new state of the art for three-dimensional signals.
The circuit is intended for use in a Tronics Microsystems three-axis accelerometric MEMS, and offers substantial electronic noise optimization and very high heat stability. It is able to withstand changes in its environment, and is suitable for applications in fields such as aerospace, geotechnical instrumentation, and high-performance automotive testing.
