应用须知
- Performing L Measurements from LDC DRDY TimingPDF, 66 Kb, 档案已发布: Nov 6, 2015
TI’s LDC1000 and LDC1101 devices measure the resonant frequency of an LC tank to determine the inductance of a sensor. Some applications require higher measurement resolution than the LDC1000 or even LDC1101 can provide. With proper configuration of the LDC, an external time measurement device can be used for improved inductance measurement resolution. - Optimizing L Measurement Resolution for the LDC161x and LDC1101PDF, 108 Kb, 档案已发布: Feb 12, 2016

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. - Measuring Rp of an L-C Sensor for Inductive SensingPDF, 205 Kb, 档案已发布: 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
