CAP1005 Overview

5 and 6 channel capacitive touch sensor

CAP1005 / CAP1006
5 and 6 Channel Capacitive
Touch Sensor
PRODUCT FEATURES
General Description
The CAP1006 and CAP1005 are multiple channel
Capacitive Touch sensors. The CAP1006 contains six
(6) individual Capacitive Touch sensor inputs while the
CAP1005 contains five (5) sensors. Both devices offer
programmable sensitivity for use in touch sensor
applications. Each sensor automatically recalibrates to
compensate for gradual environmental changes.
The CAP1005 / CAP1006 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 3uA of current. During this
mode, no sensors are active. Communications will wake
the device.
