To combat these problems, Texas Instruments (TI) FDC2214 capacitive sensing integrated circuit (IC) family offers 60x better performance in the presence of noise compared to existing capacitive-sensing solutions. The IC’s have a unique narrow-band architecture that eliminates unwanted noise and common environmental interferences. Automotive, consumer and industrial applications that previously relied on other sensing technologies can now take advantage of capacitive sensing for lower system cost and better reliability.
Design support includes a reference design for anoise-immune capacitive proximity sensor systemandFDC2214EVMandFDC2114EVMevaluation modules (EVMs).
