    SNOSCY9 – DECEMBER 2014 LDC1612, LDC1614 Multi-Channel 28-Bit Inductance to Digital Converter (LDC) for
    Inductive Sensing
    1 Features 3 Description The LDC1612 and LDC1614 are 2-and 4-channel,
    28-bit inductance to digital converters (LDCs) for
    inductive sensing solutions. With multiple channels
    and support for remote sensing, the LDC1612 and
    LDC1614 enable the performance and reliability
    benefits of inductive sensing to be realized at minimal
    cost and power. The products are easy to use, only
    requiring that the sensor frequency be within 1 kHz
    and 10 MHz to begin sensing. The wide 1 kHz to 10
    MHz sensor frequency range also enables use of
    very small PCB coils, further reducing sensing
    solution cost and size. 1 Easy-to-use – minimal configuration required
    Measure up to 4 sensors with one IC
    Multiple channels support environmental and
    aging compensation ...

    Measuring Rp of an L-C Sensor for Inductive Sensing
    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
