CAP1298, 8-Channel Capacitive Touch Sensor Controller

The CAP1298 is a multiple channel capacitive touch sensor controller.

Features

* Eight (8) 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

Applications

* Each sensor input is calibrated to compensate for system parasitic capacitance and automatically recalibrated to compensate for gradual environmental changes. In addition, the CAP1298 can be configured to detect proximity on one or more channels with an optional signal guard to reduce noise sensiti
