CAP1206 6-Channel Capacitive Touch Sensor General Description Applications The CAP1206 is a multiple channel capacitive touch Desktop and Notebook PCs sensor controller. It contains six (6) individual capaci- LCD Monitors tive touch sensor inputs with programmable sensitivity Consumer Electronics for use in touch sensor applications. Each sensor input Appliances is calibrated to compensate for system parasitic capac- itance and automatically recalibrated to compensate Features for gradual environmental changes. The CAP1206 includes Multiple Pattern Touch recogni- Six (6) Capacitive Touch Sensor Inputs tion that allows the user to select a specific set of but- - Programmable sensitivity tons to be touched simultaneously. If this pattern is - Automatic recalibration detected, a status bit is set and an interrupt is gener- - Calibrates for parasitic capacitance ated. - Individual thresholds for each button The CAP1206 has Active and Standby states, each Multiple Button Pattern Detection with its own sensor input configuration controls. Power Power Button Support consumption in the Standby state is dependent on the Press and Hold Feature for Volume-like Applica- number of sensor inputs enabled as well as averaging, sampling time, and cycle time. Deep Sleep is the low- tions est power state available, drawing 5A (typical) of cur- 3.3V or 5V Supply rent. In this state, no sensor inputs are active, and Analog Filtering for System Noise Sources communications will wake the device.
