Starterware/LDC1000: SV600983-001

Hello user,

The RP is the sensor impedance of the sensor resonant frequency. An RP value of 16.160kΩ = 16160Ω ≈ 16kΩ. This apps notes has more information on sensor design and the RP value: www.ti.com/.../snoa930

The LDC tools spreadsheet contains a calculator for this parameter: www.ti.com/.../slyc137

The LDC1000 is the most suitable LDC for metal type identification applications. For other applications, our newer devices offer many advantages over the LDC1000:

• The high-resolution multi-channel LDCs (LDC1612, LDC1614) are L-only devices which offer greatly improved measurement accuracy, better part-to-part variation, lower power consumption, easier design integration, and multiple channels.
• The mid-resolution multi-channel LDCs (LDC1312, LDC1314) are L-only devices which offer better part-to-part variation, lower power consumption, easier design integration, and multiple channels.
• The high-resolution, high-speed LDC1101 supports both L- and RP-measurements, greatly improved measurement accuracy, better part-to-part variation, lower power consumption, and easier design integration.
• The LDC2114 and LDC2112 include internal algorithms optimized for inductive touch interfaces and provide extremely low supply current in a compact footprint.

some people use comma ( , ) instead of dot ( . ) to express decimal places.
so, 1.2 could be written as 1,2 ---- both mean ' 1 and 2 tenths '.

Correct; most of Europe and many other countries use the comma as a decimal mark.
Note that TI datasheets follow the US standard (decimal point).
