DESCRIPTION
Additionally, the device includes Easy Tune enabled out-of-the-box usage even under changing noise conditions without the need for tuning - your fastest way to a touch button interface. To ensure reliable touch detection even in challenging noise environments, the MTCH2120 incorporates advanced algorithms that actively filter out noise from the signal. The MTCH2120 provides touch/proximity detection sensors that can work through plastic, wood, or metal front panels with Microchip’s proprietary Metal over Capacitive (MoC) technology. It supports a variety of conductive materials as sensors, such as copper pads on PCB, silver ink, PEDOT carbon printing on plastic film, and Indium Tin Oxide (ITO) pads.FEATURES
