DESCRIPTION

· The LDS6100/6120 family of PureTouch® controllers by Integrated Device Technology® is designed for touch-based input controls like sliders, scroll wheels, and buttons.

· Features a low-power programmable capacitance-to-digital converter (CDC) supporting up to 20 sensor inputs, with 10 configurable as direct communication mode (DCM) outputs.

· Integrated switch matrix directs touch inputs to a sigma-delta CDC for sensing changes in external sensor arrays.

· On-chip calibration logic and noise-filtering algorithms ensure robust performance and prevent false activations.

· LDS6120 models include integrated LED drivers for automatic visual feedback upon touch events without processor intervention.

· Offers SPI-compatible, I2C-compatible, and SMBus-compatible interfaces, selectable in real-time via I/F select pins.

FEATURES

· State machine architecture for ease-of-use and flexible configurability.

· Ultra-low power consumption extends battery life.

· Low BOM cost and minimal external components reduce solution footprint.

· Proprietary noise-filtering algorithms enhance touch performance.

· Customizable visual feedback effects with integrated LED drivers (LDS6120).

APPLICATIONS
