  Interfacing LDC1000 with the MSP430 LaunchPad
  PDF, 708 Kb, File published: Oct 17, 2013
  The LDC1000 is a programmable inductance-to-digital converter for use in inductance-sensingapplications. It offers a complete signal path solution between an LC tank and a microcontroller byproviding proximity and inductance data. The MSP430 is an ideal microcontroller solution for low-cost,low-power precision sensor applications because it consumes very little power. This library provides

  LDC1000 Temperature Compensation
  PDF, 308 Kb, File published: Sep 12, 2013
  LDC1000 is a high-precision Inductance-to-Digital converter with internal precision of 0.1% over dynamicrange. However, other factors may influence measurement precision greatly, dominating the systemperformance. One of these is temperature variation.This App-note will discuss the physical effects of temperature variation on inductive sensing and providemethods to mitigate these effects.

  Performing L Measurements from LDC DRDY Timing
  PDF, 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.

  Configuring Inductive-to-Digital-Converters for Parallel Resistance (RP) Variati (Rev. A)
  PDF, 255 Kb, Revision: A, File published: Jun 1, 2015
  This application note reviews sensor RP configuration for LDC devices. LDC1000, LDC1041, LDC1051, LDC1312, LDC1314, LDC1612, LDC1614 are covered in this note. Clear understanding on how to set the RP_MIN and RP_MAX registers is necessary for not only RP measurements, but also for optimum L measurements. The fundamental principle of RP measurements is that magnetic fields from an LC circuit ge

  Measuring Rp of an L-C Sensor for Inductive Sensing
  PDF, 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
