GENERAL DESCRIPTION

The CAP1106 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 auto-

matically recalibrates to compensate for gradual environmental changes.

The CAP1106 offers multiple power states. It operates at the lowest quiescent current during its Deep Sleep state. In

the low power Standby state, it can monitor one or more channels and respond to communications normally.

The device communicates with a host controller using or via SMBus / I2C. The host controller may poll the device for

updated information at any time or it may configure the device to flag an interrupt whenever a touch is detected on any

sensor pad.

A typical system diagram for the CAP1106 is shown in Figure 5-1.
