TI FDC1004QDGSRQ1

Бесконтактный датчикДаI²C3 В ~ 3,6 В-40°C ~ 125°C

Overview

Capacitive sensing with grounded capacitor sensors is a very low-power, low-cost, 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 FDC1004QDGSRQ1 also includes shield drivers for sensor shields, which can reduce EMI interference and help focus the sensing direction of a capacitive sensor. The small footprint of the FDC1004QDGSRQ1 allows for use in space-constrained applications. The FDC1004QDGSRQ1 is available in a 10-pin WSON and VSSOP package and features an I2C interface for interfacing to an MCU.
