Employing a finely tuned sigma-delta capacitance-to-digital converter and proprietary noise-filtering algorithms, each device is able to reliably sense small changes in capacitance, allowing touch-based inputs to replace a side variety of mechanical input types. On-chip automatic calibration accounts for environmental changes such as temperature, humidity, and dust and is executed automatically. The LDS6200 Family consists of four products with up to 8 capacitive sensor input pins. o o o o o o Part # LDS6201 LDS6202 Touch Sensors Up to 2 Up to 4 Up to 6 Up to 8 Package 16ld TQFN 16ld SOIC 20ld TQFN 20ld SOIC APPLICATIONS o o o o o o o o Mobile handse...
