Description

General part information

FDC2212-Q1 Series

Capacitive sensing is a low-power, high-resolution contactless sensing technique that can be applied to a variety of applications ranging from proximity detection to gesture recognition. The sensor in a capacitive sensing system is any metal or conductor, allowing for highly flexible system design.

The main challenge limiting sensitivity in capacitive sensing applications is noise susceptibility of the sensors. With the FDC2x1x-Q1 resonant sensing architecture, performance can be maintained even in presence of fluorescent light.

The FDC2x1x-Q1 is a multi-channel family of high-resolution, high-speed capacitance-to-digital converters for implementing capacitive sensing solutions. The devices employ an innovative narrow-band based architecture to offer high rejection of noise while providing high resolution at high speed. The devices support a wide excitation frequency range, offering flexibility in system design.
