Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & Community Reference Design FDC1004 SNOSCY5B – AUGUST 2014 – REVISED APRIL 2015 FDC1004 4-Channel Capacitance-to-Digital Converter for Capacitive.

General 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.

The FDC1004 is a high-resolution, 4-channel capacitance-to-digital converter for implementing capacitive sensing solutions.
