SNOSCZ4 – APRIL 2015 FDC1004Q 4-Channel Capacitance-to-Digital Converter for Capacitive Sensing Solutions
1 Features 3 Description Capacitive sensing with grounded capacitor sensors
is a very low-power, low-cost, high-resolution contactless sensing technique that can be applied to a
variety of applications ranging from proximity sensing
and gesture recognition to material analysis and
remote liquid level sensing. The sensor in a
capacitive sensing system is any metal or conductor,
allowing for low cost and highly flexible system
design. 1 Qualified for Automotive Applications
