LDC1612 LDC1614 Linear Position Sensing
PDF, 239 Kb, File published: Apr 20, 2015
This application note explains how both approaches can be used to determine the position of a target that is moved laterally above the sensor coil and provides system design guidelines for each approach. Resolution calculations are based on the 28-bit devices LDC1612 and LDC1614, but the same principles apply to other LDCs such as LDC1000, LDC1041, LDC1312, and LDC1314.

LDC Sensor Design
PDF, 1.0 Mb, File published: Mar 24, 2015
Getting the best performance out of an LDC requires a sensor suitable for the measurement. This app-note covers the parameters to consider when designing a sensor for a specific application. Specific areas of focus include the physical routing characteristics of PCB based sensors, considerations for the sensor capacitor, and techniques to minimize or compensate for parasitic effects.

Measuring Rp of an L-C Sensor for Inductive Sensing
PDF, 205 Kb, File published: Oct 1, 2015
When designing an application using TIвЂ™s LDC series of inductive sensors, it is necessary to know the L-C sensorвЂ™s equivalent parallel resistance RP at the sensorвЂ™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
