Touch sensing controllers

Analogue, Mixed Signal, LSI
Microchip has expanded its MTCH10x mTouch sensing portfolio with the turnkey MTCH102-5-8 capacitive touch controllers. In a hardware-only configuration, these 2-, 5- and 8-channel controllers replace mechanical buttons with a simple digital output, making it easy to add proximity and touch detection to any application that is constrained by size, power or cost. They support a wide range of touch-sensor shapes and sizes, feature automatic compensation for environmental conditions, and provide reliable operation in the presence of water. Moreover, active guarding increases proximity-sensing sensitivity and makes the electronic design robust, even with long board traces to the touch sensors.
