CAP1206
6-Channel Capacitive Touch Sensor
General Description
The CAP1206 is a multiple channel capacitive touch
sensor controller. It contains six (6) individual capaci-
tive 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.
The CAP1206 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.
The CAP1206 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.
