Puretouch? Capacitance Touch Ic With Integrated Touchsense -ready Haptics Driver

  The LDS6018 is a programmable capacitance-to-digital converter (CDC) designed for use with capacitive Sensor arrays implementing touch-based input controls including sliders, scroll wheels, and buttons. A built-in TouchSense?-ready haptics driver enables effcient integration of advanced tactile feedback, providing positive confrmation when a touch occurs. Touch Sensor inputs are directed through an integrated switch matrix to a 500 kHz sigma-delta CDC which senses changes in the external Sensor array. Featuring 15 Sensor inputs, the LDS6018 provides the fexibility required to implement multiple tactile-enabled touch inputs using a single controller. On-chip calibration logic continuously monitors the environment and automatically adjusts on-and-off threshold levels to prevent false Sensor activation. The LDS6018 is offered with both SPI-compatible and I 2 C-compatible Interfaces (active Interface selected by I/F select pin) and features a general-purpose input/ output (GPIO) and interrupt output for additional Communication with the host processor.
