  • LDC1312, LDC1314, LDC1612, LDC1614 Sensor Status Monitoring
    PDF, 102 Kb, File published: 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. This application note explains usage and interpretation
  • Setting LDC1312/4, LDC1612/4, and LDC1101 Sensor Drive Configuration

  • 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 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
