CAP1208

8-Channel Capacitive Touch Sensor

Datasheet

PRODUCT FEATURES

General Description

Applications



Desktop and Notebook PCs

LCD Monitors

Consumer Electronics

Appliances

The CAP1208 which incorporates RightTouch technology,

is a multiple channel capacitive touch sensor. It contains

eight (8) 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.

Features



Eight (8) Capacitive Touch Sensor Inputs

—

Programmable sensitivity

Automatic recalibration

Calibrates for parasitic capacitance

Individual thresholds for each button

The CAP1208 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.



Multiple Button Pattern Detection

Power Button Support

Press and Hold Feature for Volume-like Applications

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

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 lowest

power state available, drawing 5µA (typical) of current. In

this state, no sensor inputs are active, and communications

will wake the device.

—

5µA quiescent current in Deep Sleep

50µA quiescent current in Standby (1 sensor input

monitored)

—

Samples one or more channels in Standby



SMBus / I C Compliant Communication Interface

Available in a 16-pin 3mm x 3mm QFN RoHS compliant

package
