The Inductive Touch System Design Guide presents an overview of the typical sensor mechanicalstructure and sensor electrical design for human machine interface (HMI) button applications. Themechanical design chapter discusses several factors that impact button sensitivity, including metalselection, sensor geometry, sensitivity dependence on target-to-coil distance, and mechanical isolation - Inductive Touch - Configuring LDC2114 Touch-Button SensitivityPDF, 771 Кб, Файл опубликован: 16 мар 2017
Erroneous or unintended button presses can result in a frustrating user experience in a human machine interface (HMI). Capacitive touch buttons trigger anytime a grounded object is brought close to the button; this can often cause false or erroneous button presses. One advantage mechanical buttons have over capacitive touch buttons is that a certain amount of force must be applied on the buttons f - EMI Considerations for Inductive SensingPDF, 151 Кб, Файл опубликован: 22 фев 2017
This application note explains various EMI reduction techniques to help improve EMI performance for TI'sInductance-to-Digital Converters (LDC). Each section details a general technique with references to otheruseful online documents. A list of relevant EMI reduction techniques is provided for specific devices withinthe LDC family of products.
