CAP1298-1-SL
8-Channel Capacitive Touch Sensor Controller with Proximity Detection & Signal Guard
电容触摸传感器 8-Channel Capacitive Touch Sensor
General Description
The CAP1298-1-SL is a multiple channel capacitive touch sensor controller. It contains eight (8) 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.
Applications CAP1298-1-SL
• Desktop and Notebook PCs
• LCD Monitors
• Consumer Electronics
• Appliances
