The MTCH112-I/SN is a 2-channel Proximity/Touch Controller provides an easy way to add proximity and/or touch sensor detection to any application. The device implements either two capacitive sensors or one sensor and one active guard driver. The optional device configuration through I²C™ allows presets to be loaded in a production environment. Automatic calibration routines is used by default to choose the best options, so user configuration is not required. The MTCH112 uses a sophisticated optimization algorithm to actively eliminate noise from the signal. While the noise level is being measured, the requirements for a proximity or touch detection are updated to reflect the degree of uncertainty in the readings. When a press is detected for the first time, the threshold is automatically calibrated to choose a smart threshold for the release and next press. This creates a system that dynamically optimizes the signal to-noise ratio for its environment.
