SMSC -> Microchip
General Description
The CAP1166, which incorporates SMSC’s RightTouch® 1 technology, is a multiple channel Capacitive Touch sensor with multiple power LED drivers. It contains six (6) individual capacitive touch sensor inputs with programmable sensitivity for use in touch sensor applications. Each sensor input automatically recalibrates to compensate for gradual environmental changes.
