The LDC2114EVM from Texas Instruments is a LDC2114 1.8V 4-channel inductive touch evaluation module. The LDC2114EVM (Evaluation Module) demonstrates the use of inductive sensing to detect a button press on a monolithic piece of metal. The EVM can connect up to 4 buttons using the LDCTOUCHCOMCOILEVM or customized coils designed through Webench. Button presses & levels of pressure are indicated by onboard LEDs to indicate through onboard LEDs. The device can also be configured at different duty cycles to reduce power consumption.
Less than 7µA at 0.625 samples per second
Up to 4 buttons supported
Dedicated button logic outputs
Integrated and configurable algorithms for button press detection
LDC is controlled by an MSP430 which interfaces to a host computer
