Inductive sensing is a contactless technique for applications ranging from position or motion measurement of a conductive target to detection of spring compression or extension. Depending on the specific application, there are different system requirements regarding sensitivity, responsiveness, and power. Power consumption is a key parameter for many applications, including wearables, consumer ele - LDC1312, LDC1314, LDC1612, LDC1614 Sensor Status MonitoringPDF, 102 Kb, Archivo publicado: oct 9, 2016
TI’s multichannel inductance-to-digital converters (LDCs) LDC1612, LDC1614, LDC1312 and LDC1314feature three different methods for reporting conversion status information including errors, warnings, andcompleted conversion results. Information is available through the data registers, the status registers, andthe INTB pin of the device.

Texas Instruments’ Inductive-to-Digital Converter (LDC) technology can accurately measure with a wide variety of target sizes, shapes, and material composition. There are several target design guidelines to maximize the effectiveness of an LDC measurement system. This application note covers the relevant factors of target design that affect inductive sensing, and provides guide - Measuring Rp of an L-C Sensor for Inductive SensingPDF, 205 Kb, Archivo publicado: oct 1, 2015
When designing an application using TI’s LDC series of inductive sensors, it is necessary to know the L-C sensor’s equivalent parallel resistance RP at the sensor’s resonant frequency. The RP value changes as the target is moved; the minimum RP occurs when the metal target is closest to the sensor. The maximum RP occurs when the target is at the farthest distance. Accordingly, both values should b
