Application Notes
- Performing L Measurements from LDC DRDY TimingPDF, 66 Kb, File published: 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, File published: Feb 12, 2016

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, File published: 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
