CAP1208
8-Channel Capacitive Touch Sensor
PRODUCT FEATURES
General Description
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.
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.
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.
