SMSC -> Microchip
General Description
The CAP1106 and CAP1105, which incorporate SMSC’s RightTouch® 1 technology, are multiple channel Capacitive Touch sensors. The CAP1106 contains six (6) individual capacitive touch sensor inputs while the CAP1105 contains five (5) sensor inputs. Both devices offer programmable sensitivity for use in touch sensor applications. Each sensor input automatically recalibrates to compensate for gradual environmental changes.
