The FDC1004DSCT is a 4-channel Capacitance to Digital Converter for capacitive sensing (cap sensing) solutions. Capacitive sensing with grounded capacitor sensors is a very low-power, high-resolution contact-less 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 FDC1004DSCT is a high-resolution, 4-channel capacitance-to-digital converter for implementing capacitive sensing solutions. Each channel has a full scale range of ±15pF and can handle a sensor offset capacitance of up to 100pF, which can be either programmed internally or can be an external capacitor for tracking environmental changes over time and temperature. The large offset capacitance capability allows for the use of remote sensors.
