LDC131x/LDC161x Inductance-to-Digital Converters

The LDC1312/14 and LDC1612/14 are 2-channel inductance-to-digital converters with I²C for inductive sensing

Image of Texas Instruments LDC131x/LDC161x Inductance-to-Digital Converters Texas Instruments' LDC1312 and LDC1314 are 2- and 4-channel, 12-bit inductance-to-digital converters (LDCs) for inductive sensing solutions. With multiple channels and support for remote sensing, the LDC1312 and LDC1314 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.

LDC1612 and LDC1614 are 2- and 4-channel, 28-bit inductance-to-digital converters (LDCs) for inductive sensing solutions.
