Texas Instruments LDC1x12/14/-Q1 Inductance-to-Digital Converters
Texas Instruments LDC1312/14/-Q1 & LDC1612/14/-Q1 Inductance-to-Digital Converters are 2- and 4-channel, 12 or 28-bit inductance to digital converters (LDCs) for inductive sensing solutions. With multiple channels and support for remote sensing, the LDC1312/14/-Q1 & LDC1612/14/-Q1 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 1kHz and 10MHz to begin sensing. The wide 1kHz to 10MHz sensor frequency range also enables use of very small PCB coils, further reducing sensing solution cost and size. The LDC1x12/14-Q1 devices are AEC-Q100 qualified for automotive applications.
