Device Overview

Summary

 

The CAP1005, which incorporates RightTouch® technology, is a multiple channel capacitive touch sensor containing five (5) individual capacitive touch sensor inputs. It offers programmable sensitivity for use in touch sensor applications. Each sensor automatically recalibrates over time to compensate for gradual environmental changes.

The CAP1005 offers multiple power states operating at low quiescent currents. During the standby mode of operation, one or more capacitive touch sensors are active.

The deep sleep mode of operation is the lowest power state available drawing 3 µA of current. During this mode, no sensors are active. Communications will wake the device.
