CAP1208  
8-Channel Capacitive Touch Sensor  
General Description  
Applications  
The CAP1208 is a multiple channel capacitive touch  
sensor controller. It contains eight (8) individual capac-  
itive touch sensor inputs with programmable sensitivity  
for use in touch sensor applications. Each sensor input  
is calibrated to compensate for system parasitic capac-  
itance and automatically recalibrated to compensate  
for gradual environmental changes.  
• Desktop and Notebook PCs  
• LCD Monitors  
• Consumer Electronics  
• Appliances  
Features  
The CAP1208 includes Multiple Pattern Touch recogni-  
tion that allows the user to select a specific set of but-  
tons to be touched simultaneously. If this pattern is  
detected, a status bit is set and an interrupt is gener-  
ated.  
• Eight (8) Capacitive Touch Sensor Inputs  
- Programmable sensitivity  
- Automatic recalibration  
- Calibrates for parasitic capacitance  
- Individual thresholds for each button  
• Multiple Button Pattern Detection  
• Power Button Support  
The CAP1208 has Active and Standby states, each  
with its own sensor input configuration controls. Power  
consumption in the Standby state is dependent on the  
number of sensor inputs enabled as well as averaging,  
sampling time, and cycle time. Deep Sleep is the low-  
est power state available, drawing 5μA (typical) of cur-  
rent. In this state, no sensor inputs are active, and  
communications will wake the device.  
• Press and Hold Feature for Volume-like Applica-  
tions  
• 3.3V or 5V Supply  
• Analog Filtering for System Noise Sources  
• RF Detection and Avoidance Filters  
• Digital EMI Blocker  
• 8kV ESD Rating on All Pins (HBM)  
• Low Power Operation  
- 5μA quiescent current in Deep Sleep  
- 50μA quiescent current in Standby (1 sensor  
input monitored)  
- Samples one or more channels in Standby  
• SMBus / I2C Compliant Communication Interface  
• Available in a 16-pin 3mm x 3mm QFN RoHS  
compliant package  
• Available in a 14-pin SOIC RoHS compliant pack-
