CAP1128 - Microchip

CAP1128 8 Channel Capacitive Touch Sensor

The CAP1128, which incorporates RightTouch® 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..

Features

• Eight (8) Capacitive Touch Sensor Inputs - Programmable sensitivity - Automatic recalibration - Individual thresholds for each button
• Proximity Detection
• Multiple Button Pattern Detection
• Calibrates for Parasitic Capacitance
• Analog Filtering for System Noise Sources
• Press and Hold feature for Volume-like Applica- tions
• Multiple Communication Interfaces - SMBus / I2C compliant interface - SPI communications - Pin selectable communications protocol and multiple slave addresses (SMBus / I2C only)
• Low Power Operation - 5uA quiescent current in Deep Sleep - 50uA quiescent current in.
