Overview
CAP1293 3-Channel Capacitive Touch Sensor with Proximity Detection & Signal Guard General Description The CAP1293 is a multiple channel capacitive touch sensor controller.
It contains three (3) individual capacitive touch sensor inputs with programmable sensitivity for use in touch sensor 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 sensitivity and to isolate the proximity antenna from nearby conductive surfaces that would otherwise attenuate the e-field.
The CAP1293 includes Multiple Pattern Touch recognition that allows the user to select a specific set of buttons to be touched simultaneously.
If this pattern is detected, a status bit is set and an interrupt is generated.
The CAP1293 has Active and Standby states, each with i...
