CAP1293 - 3-Channel Capacitive Touch Sensor

CAP1293 Description

CAP1293 3-Channel Capacitive Touch Sensor with Proximity Detection & Signal Guard General .
The CAP1293 is a multiple channel capacitive touch sensor controller.

CAP1293 Features

* Three (3) Capacitive Touch Sensor Inputs - Programmable sensitivity - Automatic recalibration - Calibrates for parasitic capacitance - Individual thresholds for each button
* Proximity Detection
* Signal Guard - Isolates the proximity antenna from attenuation - Reduces syst

CAP1293 Applications

* Each sensor input is calibrated to compensate for system parasitic capacitance and automatically recalibrated to compensate for gradual environmental changes. In addition, the CAP1293 can be configured to detect proximity on one or more channels with an optional signal guard to reduce noise sensiti
