The LDC3114-Q1 is an inductive sensing device that enables touch button design for human machine interface (HMI) on a wide variety of materials by measuring small deflections of conductive targets using a coil that can be implemented on a small printed circuit board (PCB) located behind the panel. This technology can be used for precise linear position sensing of metal targets for automotive, consumer and industrial applications by allowing access to the raw data representing the inductance value. Inductive sensing solution is insensitive to humidity or non-conductive contaminants such as oil and dirt.
The button mode of LDC3114-Q1 is able to automatically correct for any deformation in the conductive targets. The LDC3114-Q1 offers well-matched channels, which allow for differential and ratiometric measurements which enable compensation of environmental and aging conditions such as temperature and mechanical drift. The LDC3114-Q1 includes an ultra-low power mode intended for power on/off buttons or position sensors in battery powered applications.
The LDC3114-Q1 is easily configured through an I2C interface. The LDC3114-Q1 is available in a 16-pin TSSOP package.

This EVM (evaluation module) is an easy-to-use platform for evaluating the main features and performance of the LDC3114. The EVM includes a graphical user interface (GUI) used to read and write registers as well as view and save measurement results. Also included is an integrated coil that can (...)
The inductive sensing calculator tools provide two Excel spreadsheets to assist in the design process for inductive-to-digital converter (LDC) devices. These tools provide coil design assistance as well as some device-specific configurations.
This reference design uses inductive and Hall-effect sensing technologies to provide a human-machine interface. The inductive sensing devices create eight different touch buttons on a seamless surface while the Hall-effect sensor is used to create a magnetic dial that can rotate and be used as an (...)
