CAP1206 6-Channel Capacitive Touch Sensor General Description The CAP1206 is a multiple channel capacitive touch sensor controller. It contains six (6) 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 CAP1206 includes Multiple Pattern Touch recognition that 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. The CAP1206 has Active and Standby states, each with its own sensor input configuration controls.
