LDC2112 / LDC2114 Inductive Sensors

Texas Instruments LDC2112 / LDC2114 Inductive Touch Buttons include an inductive sensing technology that enables touch button design. This feature can be done on various materials such as metal, glass, plastic, and wood by measuring small deflections of conductive targets. The sensor for an inductive touch system is a coil that can be implemented on a small, compact PCB located behind the panel and protected from the environment. The LDC2112 / LDC2114 can reliably detect material deflections of less than 200nm. The LDC2112 / LDC2114 is a multi-channel low-noise inductance to digital converter with integrated algorithms to implement inductive touch applications. The device employs an innovative LC resonator that offers a high rejection of noise and interference. The Texas Instruments LDC2112 / LDC2114 includes an ultra-low power mode for power on/off buttons in battery-powered applications.
