DESCRIPTION

· The LDS6100/6120 family of capacitance touch controllers from Integrated Device Technology® is optimized for touch-based input controls such as sliders, scroll wheels, and buttons.
· It 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.
· The controllers include an integrated switch matrix and sigma-delta CDC for sensing changes in external sensor arrays.
· On-chip calibration logic and proprietary noise-filtering algorithms ensure robust performance in various environments.
· The LDS6120 variant offers built-in LED lighting effects triggered by touch events without processor intervention.

FEATURES

· State machine architecture for ease-of-use and flexible configurability.
· Ultra-low power consumption for extended battery life.
· Low BOM cost and minimized solution footprint with minimal external components.
· Proprietary noise-filtering algorithms for robust touch performance.
· Integrated LED drivers for customizable visual feedback effects (LDS6120).
