FDC2114RGHR General Description

Capacitive sensing technology has revolutionized the way we interact with everyday objects, offering a contactless and high-resolution approach to various applications. The FDC2114RGHR, with its innovative EMI resistant architecture, ensures consistent performance in noisy environments, overcoming the main challenge of sensor sensitivity. This multi-channel family of capacitance-to-digital converters, such as the FDC221x and FDC211x, provides high resolution and fast sample rates for different sensing needs. With a maximum input capacitance of 250 nF, these devices enable the use of remote sensors and the tracking of environmental changes over time
