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.
