CAP1203-1-AC3-TR

The CAP1203-1-AC3-TR is a 3-channel Capacitive Touch Sensor incorporates RightTouch® technology with multiple channel. It contains individual capacitive touch sensor inputs with programmable sensitivity for use in touch sensor applications. Each sensor input is calibrated to compensate for system parasitic capacitance and automatically recalibrated to compensate for gradual environmental changes. The CAP1203 includes multiple pattern touch recognition allows the user to select a specific set of buttons to be touched simultaneously. If this pattern is detected, a status bit is set and an interrupt is generated.
