Microchip Technology CAP1188-1-CP-TR

Description

The CAP1188, which incorporates SMSC’s RightTouch® 1 technology, is a multiple channel Capacitive Touch sensor
with multiple power LED drivers. It contains eight (8) 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.
