CAP1106
6 Channel Capacitive Touch Sensor
General Description
The CAP1106, which incorporates RightTouch^® tech-
nology, is a multiple channel Capacitive Touch sensor.
The CAP1106 contains six (6) individual capacitive
touch sensor inputs. The device offers programmable
sensitivity for use in touch sensor applications. Each
sensor input automatically recalibrates to compensate
for gradual environmental changes.
The CAP1106 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, then a status bit is set and an interrupt gen-
erated.
Additionally, the CAP1106 includes circuitry and sup-
port for enhanced sensor proximity detection.
The CAP1106 offers multiple power states operating at
low quiescent currents. In the Standby state of opera-
tion, one or more capacitive touch sensor inputs are
active.
Deep Sleep is the lowest power state available, draw-
ing 5uA (typical) of current. In this state, no sensor
inputs are active. Communications will wake the
device.
